Abstract:

The most abundantly used construction material in the world is concrete. The basic materials used in the production of concrete are mined extensively, which has created a lot of pressure on the environment, leading to depleting these materials' natural sources. This creates a situation where alternate materials are being looked at, producing concrete that creates a minimum impact on the environment. This paper discusses M25 grade concrete's mechanical properties made with recycled coarse aggregate using mineral admixtures such as fly ash, GGBS, and combination. By utilizing the recycled coarse aggregate and mineral admixtures, the demand on the environment is reduced to a greater extent. This shows the direction towards making the concrete more sustainable and greener. M25 grade concrete's mechanical properties such as compressive strength, split tensile strength, and flexural strength are discussed. The results are compared with that of the normal concrete produced with natural aggregates.
