Concrete is the mostly used constructional material in industry and have versatile quality in nature. Fibrous concrete has significant factor that improve the scale and value to concrete for humid environments. Day by day abundant demand and use of concrete is increasing in construction industry. It is considered as a 2nd largest building material due to the major productivity. By the use of fibrous concrete, some bonding issues have been addressed and mitigate the environmental problems. Keeping in this view, an experimental based study is conducted to evaluate the strength of fiber reinforced concrete at different percentages 0%, 0.5%, 1.0%, 1.5% and 2.0%. All percentages are added by the weight of concrete with all fibers. In this connection, forty-five cylinders of five mixes are prepared. Workability checked of fresh concrete during the pouring of concrete cylinders. Poured cylinders’ samples are left for different curing ages at 7 and 28 days. Thirty cylinders for compression at 7 and 28days but fifteen cylinders for split tensile test at 28days with all fibers i.e. glass fiber, steel fiber, coconut fiber and polypropylene fiber. After curing, compression and split tensile tests are performed to check the strength of hardened concrete. Workability of five mixes lies between 40-90mm and compression strength is increased at 1% replacement with all fibers which is suitable for sustainable construction. Also, fibrous concrete is suitable for humid environment where high strength and voids less concrete are required like plaster in external walls and all structural components. Addition of fibers in concrete may improves the strength parameters as well as to increase the bonding and tensile properties of concrete. It reduces the quantity of water to be used in concrete. Also, the use of different types of fibers has been proved to be economical and is considered as environmentally friendly construction material.

Mortar and concrete are the mostly used construction material composed of a mixture of cement, water, aggregates (such as sand, gravel, or crushed stone), and often additional additives or admixtures. It is widely used in the construction industry for various applications due to its strength, durability, and versatility. Key characteristics of concrete include strength, durability, versatility, fire resistance, cost-effectiveness, weather resistance, insulation, and decorative options. Concrete plays a vital role in the construction industry, providing the foundation for most buildings, infrastructure, and many other structures worldwide. Its composition and properties can be tailored to meet specific project requirements, making it an indispensable material in modern construction. Various fibers can be used to enhance the mechanical and bonding properties of concrete. Additionally, waste fibers after recycling can reduce the environmental burden. Keeping in this view, glass powder sodium silicate glass (SSG) is used as a replacement of cement with different percentages 0%,5%,10%, and 15% in combination of guar gum (GG) 1% for all mixes to prepare Glass Powder–Guar Gum Concrete (GPGGC). An experimental study is conducted to investigate the mechanical and durability properties of concrete by performing compression test, flexural test, alkali silica reactivity test, sulfate resistivity test and drying shrinkage test. For this, forty-eight concrete cylinders are prepared for compression test, twelve concrete prisms for flexural test and twenty-four mortar bars of four mixes are prepared for durability testing. Workability is checked of fresh concrete during the pouring of concrete cylinders. Poured cylinders’ samples are left for 7, 14, 21 and 28 days of curing. Various tests are performed on hardened concrete and mortar samples to evaluate the mechanical and durability properties. Results concluded that workability of four mixes lies between 62-94mm and the compressive strength of concrete has been improved using glass powder (SSG). Optimum results have been achieved at 15% as compared to other mixes 5% and 10% of concrete samples. Fibrous material is used as a binding agent and fibrous concrete is suitable for humid environments where high strength and voidless concrete are required. Quantity of cement can be reduced by using different fibers as a replacement of cement. Research recommended that recycled glass powder can be used in concrete as construction material and 15% replacement is suitable for optimum results.
