In the structural engineering, use of substitute sources as building materials is recent trend, thus used concrete aggregate (RCA) from construction and demolition excess theatres an important role to preserve normal properties in growing industry as it reduces the demand for virgin aggregate and environmental influence such as pollution, energy consumption, global warming, waste disposal etc. Concrete blend of grade M25 is designed and implemented. The additional of coarse aggregate by C&D excess at regular intermissions of 0%, 25% & 50%, additional of cement by Alccofine at 10%, Fly ash at 20% and addition of basalt fibre at 0.5% to total bulk of concrete is adopted. The physical assets of material were checked as per IS code and the samples such as cube, cylinder and prism remained casted. Mechanical properties remained evaluated and the results were related with normal conventional concrete. Empirical relationships between the mechanical assets were developed and compared with those values recommended as per IS codes. From this tentative study, the cost effectiveness of natural and recycled coarse aggregate is also done. As a result, it is concluded that usage of C&D excess in concrete will decrease the necessity of natural coarse aggregate and it is economical and environment friendly. [ABSTRACT FROM AUTHOR] |
