Economic and social development of urban and rural areas continues in parallel with the increase of the human population, especially in developing countries, which leads to sustained expansion of impervious surface areas, particularly paved surfaces. The conversion of pervious surfaces to impervious surfaces significantly modifies local energy balance in urban areas and contributes to urban heat island (UHI) formation, mainly in densely developed cities. This paper represents a literature review on the causes and consequences of the UHI and potential measures that could be adopted to improve the urban microclimate. The primary focus is to discuss and summarise significant findings on the UHI phenomenon and its consequences, such as the impact on human thermal comfort and health, energy consumption, air pollution, and surface water quality deterioration. Regarding the measures to mitigate UHI, particular emphasis is given to the reflective and permeable pavements.

The reactivity effect of calcium carbonate, present in ground oyster shells and limestone filler, on the formation of carboaluminate phases in ground granulated blast furnace slag blended cement pastes was reported in this paper. Six different binary and ternary blended cement pastes were prepared using ground granulated blast furnace slag, ground oyster shells and limestone filler with different replacement levels (from 5 to 35%). The carboaluminate formation was assessed and quantified directly using X-ray diffraction (XRD), and indirectly by following the aluminate phase’s reaction (heat flow) and consumed calcium carbonate using Isothermal Calorimetry (IC) and Thermogravimetric Analysis (TGA), respectively. Further, the overall reaction degree calculated based on TGA results and the compressive strength were determined to support the findings obtained. The results revealed that the calcium carbonate present in ground oyster shells is more reactive when compared to that present in limestone filler, where more formed hemi- and monocarboaluminate phases were observed in mixtures containing ground oyster shells. An enhancement in compressive strength and overall reaction degree was observed by adding 5% ground oyster shells as cement replacement.

This paper presents the preliminary findings on a new mortar prepared with alkali-activated seashell waste (AASW). Three mortars were manufactured with seashell waste to Activator ratios of 2.5, 3 and 3.5. The mechanical properties were determined, and the chemical products of each mixture were characterized using TG/DTG, XRD and FTIR analyses. From both an economic and an environmental point of view, the obtained results are very encouraging where they show that SW can be used as precursor to formulate an alkali-activated mortar with a compressive strength of 22 MPa and a porosity of 16.5%. The AASW paste was found to be mainly composed of C-S-H and different carbonates such as gaylussite, pirssonite and thermonatrite. In terms of mechanical strengths and porosity, it was established that the water to binder ratio is the key factor. Furthermore, the microstructural images showed a good compatibility between the AASW paste and aggregates.

The purpose of this paper is to study the long-term durability and bio-colonization of concrete in marine environment. In this work, concrete formulations were developed and optimised by varying the type of cement (CEMII and CEMV) and introducing shellfish by-products (Oyster Shells) into their composition (by substituting 20% by weight of 4/10 aggregates). Four concrete formulations were thus studied. The durability of these materials upon bio-colonization were tested after 90 days, 180 and 360 days of immersion in natural seawater. The monitoring of the photosynthetic activity of biofilms and the biomass on the materials surface showed a better acclimatisation of the microphytobenthos in CEMII 20% Shells concrete than in other concretes despite a lower colonization on this concrete. It was also noticed that the chlorophyll biomass was the highest in concrete CEMV 20% Shells after 360 days. During immersion, the mechanical strengths of CEMII 0% Shells, CEMII 20% Shells and CEMV 20% Shells increased. At long term of immersion, the chloride ions diffusion was more reduced, in natural seawater, for CEMII 0% Shells, CEMII 20% Shells and CEMV 20% Shells concretes than for concrete CEMV 0% Shells. these results lead to the assumption that the accumulation of biofilm plays a role as protective barrier against the action of chloride ions. Finally, it appears that the concrete CEMII 20% Shells is the most suitable concrete mix design for marine infrastructure amongst the tested designs.

Climate change is leading construction engineers and building stakeholders to improve materials thermal insulation and heat storage capacity. The development of energy efficient building materials with a low environmental impact is a real challenge. In this sense, earth-based materials are known worldwide and have been used since thousands of years. These materials present many advantages but their deployment on a large scale, while respecting the operative standards, is still limited.

The European flat oyster, Ostrea edulis, is an important ecosystem engineer that has been progressively disappearing from European coasts over the last century mainly due to overexploitation, habitat degradation and disease. It is now the subject of many conservation and restoration programs throughout Europe, including the Flat Oyster REcoVERy (FOREVER) project in France. Protecting and managing the remaining populations has become a nature conservation priority because this species is able to build biogenic reefs, very specific habitats that provide many ecosystem functions and services. The availability of suitable hard substrates for larval fixation is a critical factor during this reef-building process. Although natural substrates are in short supply, production and deployment is an easy step to help oyster reef restoration. The present study was carried out to improve artificial reef design and the composition of the concrete used to build them, focusing on the impact of concrete formulation and surface texture on larval settlement in the field. Nine bio-sourced concrete formulations and ten surface textures were evaluated. The number of settled larvae counted on each concrete substrate reflected their preferences, and results demonstrated that microscale surface texture has a greater impact on recruitment than concrete formulation, with larvae preferring to settle in depressions on a rough rock-like texture and avoiding flat, horizontal and exposed areas. Physical and mechanical properties of the different formulations were also evaluated. Although they had almost no impact on recruitment, these results could be helpful for artificial reef-building (in terms of 3D design, durability, manufacture and deployment) and guide choices of materials that should be used and the proportion and granulometry of incorporated shells to obtain the best surface texture.

In this study, two methods were used to measure the carbonation depth of coconut fibre-reinforced mortars that were prepared from Portland cement (PC) and calcium sulfoaluminate cement (CSA cement), including traditional phenolphthalein reagent and thermogravimetric analysis (TGA). Accelerated carbonation was conducted at 4% CO2 concentration, temperature of 20 °C and 65% relative humidity (RH) within 12 weeks. Complete carbonation was detected in the CSA cement-based mortar while PC-based mortar was carbonated partially according to both methods used. The difference in carbonation depth, however, is observed as soon as the reagent and TGA measurement were applied. The significant effectiveness of the carbonation process on the microstructure changes and mechanical characteristics of the cementitious matrix is highlighted through analysis of the change in the quantity of calcium carbonate (CC) and portlandite (CH) on the different mortar profiles and comparison with natural cured samples.

Protection, restoration, and regeneration of aquatic habitats are an increasingly important issue and are requiring intensive research. In the marine environment, artificial reefs may be deployed to help offset habitat loss, increase local biodiversity and stimulate the recovery of ecosystems. This study aimed at the fabrication of artificial reefs by 3D printing. In the framework of the European INTERREG Atlantic Area collaborative project “3DPARE”, six printed concrete formulations with limited environmental impact, based on geopolymer or cement CEM III binders and recycled sands, were immersed in the Atlantic along British, French, Portuguese and Spanish coasts. The colonisation of the concrete samples by micro- and macroorganisms and their durability were assessed after 1, 3 and 6 months of immersion. Results showed that both parameters were better with CEM III compared to geopolymer-based formulations. Therefore the use of CEM III should be prioritised over these geopolymer binders in 3D printed concrete for artificial reef applications.

The main objective of this study is to develop non-autoclaved insulating foam using bio-based materials. The bio-based materials used in this work were flax fibres of different lengths and hemp aggregates. The study was conducted as follows: First, the reference formulation, manufacturing process, and swelling height were optimized. Furthermore, several parameters such as the drying temperature, maturation time, water/sand ratio, quantities of the expansion agent, and the amount of cement required were analysed. Second, the bio-based insulating foam was optimised. Based on the reference composition, flax fibres that were 6 and 18 mm in length and hemp aggregates ranging from 2 to 25 mm in length were incorporated into a reference cementitious foam individually and in combinations. Finally, the physical, mechanical, and thermal behaviours of the bio-based insulating foam were studied. The results obtained for the swelling of the insulating foams were based on a well-structured process that respected the cure conditions and the experimental protocol. The bio-based insulating foam had better thermal conductivity that can reach 0.100 W/m·K. This value was equivalent, for example, to the thermal performance of wood with a density of approximately 435–565 kg/m3, or autoclaved cellular concrete with a density of 400 kg/m3. Furthermore, the bio-based insulating foams achieved compressive strengths of 0.15 MPa, which is almost equivalent to traditional insulating materials such as Batibord-based perlite. This compressive strength can be improved by increasing the quantity of the cement used and the density of the mixture.

In order to reduce the dependency on conventional materials and negative environmental impacts, one of the main responsibilities of the construction field is to find new eco-friendly resources to replace the traditional materials partially. Natural fibers were known as potential candidates for the reinforcement of structures in civil engineering by virtue of their advantages. Among the different kinds of vegetable fibers, coconut fiber has been exploited in a limited way over the past few years. This paper aims at evaluating the different properties of local coconut fibers (Vietnam). Several laboratory tests provide geometrical, physical, mechanical properties and durability properties that are compared with literature results obtained from similar natural fibers. The local coconut fibers tested demonstrated properties suitable for reinforced mortars. With adequate control of their preparation, they could be reused in the manufacture of mortars in the construction.

In this study, we attempt to improve the energy efficiency in the precast concrete industry by eliminating thermal treatment and reducing the environmental impact of concrete by using ground granulated blast furnace slag (GGBS) and ultrafine Portland cement (UC). We studied several substitute materials such as UC and GGBS with ultrafine and standard particle fineness values. Thermal treatment is used in the prefabrication industry to achieve concrete with high strength at an early age (~13 h) and allow continuous production. UC was added to study the possibility of eliminating steaming by replacing it with an exothermic reaction generated by the UC. GGBS was used as a partial substitute for cement to reduce the carbon dioxide emission footprint produced by the cement industry. The compressive strength following the addition of UC was encouraging. A 90% evolution at an early age was observed for concrete samples with 42% UC and 42% GGBS with heat treatment. In addition, when using the same composition, a 66% increase was observed without heat treatment. The use of GGBS or fine particles improved the carbon footprint without compromising the compressive behaviour of the concrete.

This study aims to valorize duvet waste notably polyester and duck feathers in the conception of thermal insulation for buildings. Physical properties of these waste materials were investigated and mini-prototypes were designed by varying the components. Thermal conductivity tests showed that those manufactured with polyester and duck feathers have approximately the same thermal conductivity which is around 0.05 W/(m∙K). However, fire reaction tests demonstrated that polyester has a better fire behavior than duck feathers which produce a larger amount of ignited debris. Thus, the mini-prototype based on polyester was selected for full-scale reproduction and characterization. To do so, a Hot Box system was designed and developed. The full-scale tests confirmed the interesting thermal properties of the polyester, already obtained at a reduced scale.

In recent years, the innovations in the construction industry have developed remarkably. Using the waste materials and co-products coming from different industries, became an alternative to recycle and producing new eco-friendly materials from the wastes left behind by the industries. In present study, Wastepaper Sludge Ash (WSA) and Ground Granulated Blast-furnace Slag (GGBS) which is known, as a cement replacement and cementitious material in construction industry in recent research, are the by-products reused. They mixed and activated to obtain a binder matrix for manufacturing dry-mortars in construction industry. The objectives are to valorize the maximum reuse of WSA and to substitute cement in the mortar composition and also to recycle and reuse wastes in respect of circular economy. This paper aimed to observe the mechanical properties of these innovated mortars. The binder matrix for dry-mortar manufacturing is a non-cement matrix and is composed of 72 wt. % of WSA and 28 wt. % of GGBS, considering that GGBS should be 7% of total mass of the mixture without cement, water and any activators addition. Two types of non-cement mortars have been investigated. Mortars without any activators and the ones with three types of activators to improving the maximum reactivity at early age. These activators are: sodium carbonate, sodium silicate and calcium chloride. WSA contains 20% SiO2 and 50% CaO, and respectively 35% and 43% for GGBS, which are close to the one of cement and that can develop pozzolanic properties in the absence of cement. The condition of curing is carried out at 20 °C, for 2,7 and 28 days for all the prismatic samples with the dimension of 40 × 40 × 160 mm3. Mechanical tests i.e. compression and tension by bending, are performed after 2, 7 and 28 days to determine the mechanical strengths compared with those of normal mortars. A maximum compressive strength for non-cement binder matrix is 13.7 and 11.1 MPa, which obtained in the presence of calcium chloride and sodium silicate respectively after 28 days.

The large quantities of seashells produced in the North-West of France and the depletion of quarries motivates the research of new sources of aggregates. This article examines the influence of incorporating crushed queen scallop shells on ordinary concretes in order to assess the feasibility of reusing marine by products in the form of aggregates. For this purpose four different concrete mixes were produced, one of them used as reference with natural aggregates and the others prepared with 20, 40 and 60 % of crushed queen scallop shells replacing the natural aggregates. Concretes were characterized at fresh state by its workability, the air content and the density, and at hardened state by the mechanical and durability properties. The incorporation of crushed queen scallops causes an increase of the entrapped air of concrete, a reduction of the mechanical properties and an increase of the concrete porosity facilitating the transport of fluids and chloride ions in concrete.
