Abstract: Glass is widely used in our lives through manufactured products such as sheet glass, bottles, glassware, and vacuum tubing. Glass is an ideal material for recycling. The use of recycled glass helps in energy saving. The recycled glass has significant contributions to the construction field for concrete production. The application of glass in architectural concrete still needs improvement. Many experiments were conducted to explore the use of waste glass as coarse and fine aggregates for both ASR (Alkali-Silica-Reaction) in concrete. The accumulation and management of construction and demolition waste, which increases along with the continuous spreading of urbanization and industrialization. Construction and demolition waste can be recycled and used as a raw material for new applications. Recycled brick aggregates recovered from demolished masonry structures can be utilized in the manufacture of new concrete mixtures. Hence, partial replacement of fine aggregate by the other compatible material like sintered fly ash, crushed rock dust, quarry dust, glass powder, recycled concrete dust, and others are being researched from the past two decades to conserve the ecological balance. additional plasticizers have been used for this project for improving their workability. In this project experimental studies on the concrete of M20 grade with partial replacement of fine aggregates by crushed brick powder (replacement by 5%, 10%, 15%,20%,30%) and crushed glass powder (replacement by 5%, 10%, 15%). The compressive strength of M20 grades of concrete at different days (3 days 7 days, 28 days) has been determined along with the measurements of workability in the slump test. The trial cubes were cast and tested at different stages. When fine aggregates are replaced by 30% crushed brick powder. The decrease in strength at the end of 28 days was found to be ranging from 22.2% and 9.81%. when fine aggregates are replaced by 20% crushed glass powder, decrease in the targeted strength at the end of 28 days was found to be ranging between 3.0%and 8.6%. The slump value was found to be decreasing in the case of crushed brick powder, while it was found increasing substantially in the case of glass of glass powder. A combination of both alternatives i.e., brick powder (20%) and glass powder (15%) were also studied and it was found that the compressive strength at the end of 28 days for M20 grade of concrete is 96.13%.
