Abstract
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.
