摘要：In India a huge quantity of construction and demolition wastes are produced every year. These wastes require a large place to dump and hence the disposal of these wastes has become a problem. Also the continuous use of natural resources for making conventional concrete leads to the reduction in their availability and results in the increase of the cost of the aggregates. When recycle concrete aggregate is used in the structural concrete, the assessment of physical, mechanical and durable characteristics are very important. The physical and mechanical properties of natural aggregate and recycle aggregates are characterised. The experimental investigation was done on the M30 grade of concrete. A control specimen was created with 100% recycled aggregate at different concentration of alkaline activator (10M, 12M and 14M) and this specimen compared with a conventional concrete. Cube compressive strength of geopolymer concrete with recycle concrete are evaluated. A total 24 cubes were casted to determine the compressive strength at 7 days and 28 days. As the concentration of alkaline activator is increased, the early strength of specimen increased.
