USAGE OF RECYCLED AGGREGATE IN CONSTRUCTION WORKS
Abstract
Construction waste is growing expeditiously with the dramatic increase in the number of demolitions of old constructions across the world. Therefore, it has led to social as well as environmental concern in recycling process of the construction waste. The material used extensively for construction across the world is concrete and mostly it has been incorporated in all kind of civil engineering works. Since, 70-80% of the concrete volume comprises of aggregates, it will be judicious enough to utilize the recycled aggregate again. Based on the report of researchers, it can be concluded that recycled aggregates from concrete is acceptable for non-structural construction works. In this paper, a comprehensive investigation has been conducted by testing of the properties of the recycled aggregates and studying the results. Basic properties such as compressive strength, flexural strength, Split tensile strength are explained here for different combinations of recycled aggregate with natural aggregate. Study has shown that the strength of concrete using partial proportion of recycled aggregates could reach substantially similar strength compared to concrete having freshly used natural aggregates. Substantially, prevailing status of recycled aggregate in India along with its need about the time ahead and its prosperous implementation are discussed here.
