A STUDY ON THE USE OF CONSTRUCTION AND DEMOLITION WASTE AS COARSE AGGREGATE IN SELF-COMPACTING CONCRETE FOR SUSTAINABILITY

摘要

In this experimental study, a simple unique mixture proportioning method starting with volume of paste was successfully adopted for developing self - compacting concrete (SCC) using construction and demolition waste as recycled concrete aggregate, for sustainability. A systematic experimental programme with wide range of volume of paste, powder, water, and cement contents were chosen keeping in mind the field requirements. Results showed increase in compressive strength as paste volume is increased for the same w/c ratio and higher compressive strength when compared to normal concrete. The enhancement in compressive strength can be factored in the mix design. SCC can be the preferred choice when recycled coarse aggregate are used.
