Abstract
The utilisation of stone waste, in the form of mineral admixture as a pozzolanic and non-pozzolanic material for mortar and concrete has received considerable attention in recent years. This interest is part of the widely spread attention directed towards the utilisation of wastes and industrial by-products in order to minimise Portland cement (PC) and sand consumption, the utilisationof which being environmentally damaging. Another reason is that mortar and concrete, which contain pozzolanic as well as non-pozzolanic materials, exhibit considerable enhancement in durability properties. This paper reviews work carried out on the use of stone waste as a partial non-pozzolanic replacement for sand in mortar and concrete and in the containment of hazardous wastes. The literature demonstrates that different stone wastes is an effective inert filler which causes great improvement in the pore structure and hence the resistance of the concrete to the action of harmful solutions.
