Abstract

In this context studies were conducted to use waste glass powder to partially replace sand in concrete. Waste glass powder can be defined as a powder that is obtained by crushing waste glasses which are left over while making glass products to form fine particles less than 4.75mm. Concrete is very strong in compression, but its tensile strength is only about 10% of its compressive strength. Also, concrete is brittle in nature. In plain concrete, structural cracks develop even before loading, particularly due to drying shrinkage or other causes of volume change. In order to arrest the cracks and to improve the properties of concrete, small, closely spaced and uniformly dispersed fibers can be added along with the concrete. This type of concrete is known as fiber reinforced concrete. Many in the concrete construction industry as familiar with the design, construction, performance and benefits of steel fiber reinforcement, but new technologies and research are showing surprising results. This project presents the feasibility of the usage of waste glass powder as partial substitute of fine aggregate in concrete. Compressive strength of concrete cubes made with partial replacement of fine aggregate with waste glass powder of different ratios with constant water-cement ratio of 0.45 are evaluated and compared with conventional concrete and also flexural strength of steel fiber reinforced concrete mixed with optimum amount of waste glass powder is assessed.
