Indian Concrete Journal - ICJSummary: The recycling of waste concrete is beneficial and necessary for the environmental preservation and effective utilization of natural resources. The use of recycled coarse aggregates obtained from construction and demolition waste in new concrete is a solution for effective utilization of construction and demolition waste. In this study, natural aggregates were replaced 100% with recycled aggregates obtained from demolished concrete. Experimental investigations have been carried out on concrete prepared using recycled coarse aggregates obtained from three different sources (Laboratory waste, building of age 10 years and 30 years) and by using two types of jaw crushers, one with flat jaws and other having jaws like V-grooves. Results showed that crushing type of concrete for manufacturing recycled aggregate have a marginal effect on concrete properties. However, there is no significant variation observed in the properties of concrete made with recycled aggregate prepared from different sources (Laboratory waste, building of age 10 years and 30 years).
