Properties of high strength concrete utilizing processed recycled aggregate

Abstract

Globally the utilization of concrete particularly highstrength concrete has been increasing day by day due to rapid industrialization and infrastructural developments An enormous quantity of natural coarse aggregate is required for making concrete to meet the huge demand The natural resources of coarse aggregate are depleting rapidly all over the world and urgently need to be conserved On the other hand millions of tonnes of construction and demolition wastes are being generated from different sources The disposal of these huge quantities of C and D waste is posing a big problem to the local administration and environment Further there are areas where the natural coarse aggregates are scarcely available and are hauled from long distances These issues have to be addressed urgently A review of the literature suggests that obtaining the coarse aggregates from C and D waste is a possible solution to these issues Therefore in the present work an experimental attempt has been made to utilize the recycled coarse aggregate from C and D waste to the maximum possible extent for producing the high strength concrete
