Considering the remarkable characteristics of nanomaterials, previous research studies investigated the effects of incorporating different types of these materials on improving the concrete properties. However, further studies are required to evaluate the complementary hybridization and synergistic influence of nanomaterials. In this research, the combined effect of adding nano silica particles (NS) and multi-walled carbon nanotubes (MWCNT) on enhancing both the compressive and flexural strengths of the cement paste was investigated. Moreover, the morphology of the interface between cement paste and aggregates was studied by scanning electron microscopy (SEM). The mixtures were prepared using three different portions of MWCNT and NS. Electron microscopy images indicated a uniform distribution of nanoparticles in the cement matrix, enhanced hydration reactions, and increased density. Based on the experiments’ outcomes, the combined utilization of silica and carbon nanomaterials in the cement paste did not necessarily result in the maximum compressive and flexural strengths. Furthermore, it was observed that the use of higher percentages of pristine NS in the absence of MWCNT can lead to further enhancement of strength properties of the cement paste.

The durability of concrete against penetration of chloride ions is one of the most important factors that can affect the serviceability of structures. Many tests can measure or predict the durability of concrete structures during their lifespan. Recently, many researchers have tried to provide different relationships and correlations between durability tests. The rapid chloride migration test, the electrical resistivity test and the water absorption test are some of the common and practical tests that may be used for studying the durability and permeability of cementitious materials. Providing an empirical correlation among these tests could yield the opportunity to estimate the durability parameters. This study presents relationships between durability tests and their correlations with the compressive strength in mortars containing rice husk ash, nanosilica and sugar cane bagasse ash. The empirical correlation between electrical resistivity and the migration coefficient followed the Nernst–Einstein equation. A strong linear correlation between electrical resistivity and compressive strength of binary mixtures was found, whereas a weak correlation was found for ternary mixtures. Moreover, a strong power correlation between electrical resistivity and capillary absorption of mortars was found.

The objective of this study is to assess and compare the effects of different nanoparticles, namely nano-TiO2, nano-Al2O3 and nano-Fe2O3, on the performance of self-consolidating concrete (SCC) in terms of fresh, mechanical, and durability properties through performing different experiments. TiO2, Al2O3, and Fe2O3 nanoparticles with the average diameter of 18, 15, and 14 nm were used with two different contents of 3% and 5% by weight of cement. For assessing the fresh properties of SCC, slump flow, V-funnel, L-box, and column segregation tests were conducted. For the mechanical properties, compressive strength of concrete was investigated, and for the durability properties rapid chloride migration (RCM), electrical resistivity, rapid chloride penetration (RCP), and water penetration depth tests were carried out. The result showed that the workability properties of the mixes slightly improved by 3% addition of nanoparticles while increasing this value to 5% decreased the workability. For higher content of nanoparticles, the incorporation of nanoparticles in the mixes increased the water demand and consequently caused a reduction of workability. For compressive strength, nano-Fe2O3 showed a superior effect on the enhancement of strength in comparison to nano-Al2O3 and nano-TiO2. This observation was attributed to the formation of calcium ferric hydrate (C-F-H) gel in the microstructure. Moreover, the addition of all the nanoparticles resulted in an improvement of durability properties. High surface area of nanoparticles provided nucleation sites for cement particles and expedited the hydration process development. The formation of a higher content of hydration products helped the densification of microstructure. Moreover, nanoparticles controled the growth pattern of C-S-H gel, which led to the formation of a homogenous microstructure with smaller pore sizes and consequently to lower permeability against penetration of aggressive ions i.e., chloride. It is concluded that partial replacement of cement with nanoparticles on average improved the compressive strength and durability properties of SCC, but resulted in a reduction of workability.

Environmental concerns have increased due to the amount of unused/expired plastic medical waste generated in hospitals, laboratories, and other healthcare facilities, in addition to the fact that disposing of such wastes with extremely low degradation levels causes them to remain in the environment for extended periods of time. These issues have led researchers to develop more environmentally friendly alternatives for disposing of plastic medical waste in Australia. This study is an attempt to assess the impacts of using expired plastic syringes as fine aggregate on fresh and hardened characteristics of flowable concrete, which might provide a solution to environmental concerns. Six mixtures of flowable concrete with water-to-cement ratios of 0.38 were studied. It was found that using recycled aggregate in up to 20% can improve the workability and increase the V-funnel values of flowable concrete mixtures. However, using waste aggregates in more than 30% caused an inapt flowability. Adding waste aggregate at the 30%–50% replacement level led to a decrease in the L-box ratio. To verify the utility and the efficacy of this experiment, the connections between different rheological test measurements were also compared by implementing the Pearson correlation function. The mechanical properties of the mixes containing recycled aggregates were decreased at the age of seven days; however, at later ages, waste aggregates increased the strength at the 10%–30% replacement levels.

The study researched the effectiveness of four polymer admixtures (3%, 5%, 10%, and 15% of water weight) on the fresh and hardened properties of self-compacting concrete (SCC) cast using recycled and natural aggregates. Results show that polymer additives had positive effects on the fresh properties of SCC using recycled aggregates. Incorporating polymer additives increased the filling ability of concrete by more than four times. All polymer modified SCCs had a 100% passing ability compared to the 80% passing ability of the control samples. The compressive strength of materials at similar polymer ratios decreased by about 50% when natural aggregates were replaced with recycled aggregates. The flexural strength of SCC including recycled aggregates with 15% polymer was maintained compared to the control SCC including natural aggregates. The addition of 15% polymer to recycled aggregates concrete could improve workability and maintain flexural strength.

This paper presents a method for easy calculation of the optimum dimensions of the shear walls openings based on deformation and displacement of the wall in the roof elevation with the usage of the continuous method. By using the continuous method, researchers have tried to calculate the relationship between the displacement of the wall in the roof elevation with the openings dimensions. The displacement diagram of the wall at roof elevation will be plotted with respect to the defined parameters of the openings length to the walls length ratio and the percentage of the openings area to walls area ratio. Then, the openings dimension, which led to minimum displacement, will be chosen, and its alterations diagram versus the walls dimensions will be plotted. The effect of the parameters, such as the number of floors and loading type on the calculated optimum dimensions, which may change the results, has been shown. Two case studies of coupled shear wall under lateral load were considered. In both of them, the openings areas were analyzed with the ETABS program, first with optimal dimensions and then with non-optimal dimensions. The results were compared, and a simple method was presented for the calculation of the optimized dimensions of openings.

Alkali-activated materials (AAMs) have recently been used as a suitable replacement for conventional ordinary portland cement (OPC) mixtures. This study evaluates rheological, injectability, and mechanical properties of alkali-activated slag (AAS) mixes to assess the possibility of using AAS pastes as coating mortars for the rehabilitation of concrete structures. Mixtures are produced with the incorporation of silica fume (SF) up to 15% of total binder weight in AAS pastes. A combination of sodium hydroxide (NaOH) and sodium silicate (water glass) is used to activate aluminosilicate sources. Water glass:NaOH ratios of 0.4 and 0.5 and activator solution:pozzolan ratios of 0.55 and 0.65 are selected after initial attempts to evaluate the effect of activator solution characteristics on the rheology properties of AAS mixtures. Samples are prepared in two moisture conditions (dry and damp) in order to assess the effect of moisture presence on the performance of AAS injection pastes. Setting time, fluidity, injectability, tensile strength, capillary absorption, and slant shear tests are conducted on AAS pastes. Microstructure analysis is performed on the selected mixtures. According to results obtained from limited experimental work conducted in this study, 5% SF addition results in higher setting time and injectability of AAS pastes. In addition, it is found that an increase in water glass content in AAS pastes results in lower setting time and fluidity, which in turn results in a low level of injectability. The results of tests conducted on damp and dry samples show a high level of compatibility of AAS paste with moisture presence.

The influence of sugarcane-bagasse ash (SCBA) and rice-husk ash (RHA) as cement replacement materials on the mechanical and durability properties of mortars was investigated in this study. Portland cement was replaced by RHA and SCBA at a rate of 10–30% and 10–25% by weight of cementitious materials, respectively. Also, ternary mixtures were prepared by the incorporation of both additives. Replacement dosages were selected based on the former research studies to cast the mortar. Additionally, a control mixture, containing only cement, was prepared to clarify the effectiveness of replacement materials. Compressive strength tests were conducted to evaluate the mechanical performances of the specimens. In addition, the transport tests (water absorption and capillary absorption), electrical resistivity, rapid chloride migration test (RCMT), and acid resistance of mortars were evaluated in order to investigate the effect of SCBA and RHA on the durability properties of mortar. Results showed that RHA was more effective at enhancing the mechanical properties of mortars than SCBA. However, according to the durability tests’ results, both SCBA and RHA were found to be effective since ternary mixtures were more durable when compared to the control mixture.

The purpose of this study is to measure the effects of increasing the specific surface area of perlite natural pozzolan in self-compacting concrete (SCC) by the mechanical milling method. The use of SCC in construction projects allows for a reduction of human resources and equipment, which significantly decreases the labor cost and time of construction. SCC often needs chemical additives to achieve workability requirements. However, the usage of a greater amount of chemical additives as well as cement materials in the mixing designs increases the cost of mixing. Incorporation of inexpensive natural pozzolans as an alternative to cementitious materials can improve the fresh properties and durability of concrete. Moreover, reducing the hydration heat and controlling the shrinkage of SCC mixtures, which mainly contain significant amounts of powdered materials, is another benefit of the natural pozzolans. However, the reactivity of natural pozzolans, specifically in the early ages, is always a concern when using these supplementary materials. In this study, several methods have been proposed to improve the reactivity of these materials. Increasing the specific surface area of pozzolanic materials by mechanical milling is one of the most economical and efficient methods implemented so far. This study measured the performance of various levels of perlite powder, a natural pozzolan, for fresh, mechanical and durability properties. In addition, the effects of increasing the specific surface area of perlite powder on properties of concrete were measured and evaluated. According to the results, an increase in the specific surface of perlite powder improved the compressive strength and durability index as a result of increased reactivity. This was accompanied by a substantial improvement in the properties of SCC mixtures in the workability and stability tests.

Over the last few decades, polymer concrete (PC) has been finding use in quick repairing of concrete structures. However, there have been only few studies on the mechanical behavior of PC. The aim of this study is to evaluate the mechanical behavior of PC using destructive and non-destructive tests (NDT). The mixtures were prepared with three different polymer ratios (10%, 12%, and 14%) and two different coarse aggregate sizes (4.75–9.5 mm and 9.5–19 mm). The samples were subsequently tested under three different temperatures (−15 °C, +25 °C, and +65 °C). The Taguchi method and analysis of variance (ANOVA) were used to optimize PC mixes based on the compressive, splitting-tensile, and flexural strengths under varying polymer content, coarse aggregate size, and temperature. NDTs, including ultrasonic pulse velocity and electrical resistivity tests, were carried out to gain insights into the porosity and void content of the specimens. Scanning electron microscopy (SEM) was used to analyze the bonding interface between aggregates and polymer, microstructure phase, and pores that were present in the structure of the PC. Results show that a decrease in the temperature from +25 °C to −15 °C led to an improvement in the mechanical properties of PC mixes, whereas an increase in the temperature from +25 °C to +65 °C adversely affected the mechanical properties. Based on NDT, it was found that increasing the coarse aggregate size and polymer ratio reduced the porosity of specimens. This is attributed to the decreased surface area to volume ratio with increasing particle size, which allowed the polymer to completely coat the surface of aggregates. Finally, a set of expressions was proposed to predict the mechanical properties of PC.

The objective of this study is to develop the durability of mortar mixtures against combined chloride and sulfate deterioration by replacing a certain amount of limestone cement with titanium dioxide (TiO2). Marine environments contain high concentrations of chlorides and sulfates. To improve the concrete durability within such conditions, it is important to control the concentration of both ions. The application of TiO2 in concrete has been increasingly considered in recent years. However, the durability issues of mortar made with TiO2 have not been evaluated. To achieve this purpose, an experimental program was designed to assess five different corrosive solutions of chloride and sulfate to investigate different partial cement replacement by TiO2. The compressive strength, surface electrical resistance, mass change, dynamic modulus of elasticity, Rapid chloride migration test (RCMT), Rapid chloride permeability test (RCPT), and half‐cell energy were tested in the binary and ternary solutions. Results indicated that using these nanoparticles as a partial replacement of cement developed the pore structure of the mortar, leading to the improved durability of the mortar and less deterioration in control specimens. Also, the chloride penetration increased by adding sulfate content at early age immersion. With little to no TiO2 in the mortar specimens, chloride ions mitigated the corrosive influences of a sulfate attack.

Environmental conditions, such as temperature and relative humidity, impact the rate of evaporation, mechanical properties and durability of concrete. Thus, they have a direct effect on the development of transport properties. The purpose of this study is to investigate the effect of controlled environmental conditions on moisture retention, dielectric constant (DC), compressive strength, shrinkage, water sorptivity index, rapid chloride migration test (RCMT), microscopical analysis (thin sections) and electrical resistivity. The mortar specimens were prepared using Ordinary Portland Cement with two water-to-cement ratios of 0.42 and 0.52. The specimens cured in the controlled environments of 25, 46 and 65 °C for temperature, and 30% and 90% for relative humidity. The results showed that curing under higher temperature cause reduction in compressive strength and increase in the sorptivity index. Moreover, a great correlation between DC measurements and sorptivity, the RCMT and electrical resistivity was found. Higher relative humidity helped the performance of samples, considering the durability and mechanical properties.

The damage that frequently occurs on pavements will affect the safety and comfort of road users. Road surface conditions’ assessment is a way to determine the type of program evaluation that needs to be done. The purpose of this research was to assess the structural conditions of pavements with non-destructive tests, such as pavement condition index , falling weight deflectometer, total pavements acceptance device and ground penetrating radar. The descriptive study was conducted to compare the road conditions’ assessment data that resulted from different methods for analysing the results of the road evaluation. This study was carried out at Victoria Regional Airport and focused on the analysis of the runway 13R that had two main sections.
