Abstract
Recycled aggregate concrete can utilise demolition material from concrete and masonry constructions. Though several studies have been made on the reuse of concrete waste, only limited studies have been made with respect to use of demolished brick masonry as aggregate. An attempt has been made in this paper to assess the physical and mechanical properties of recycled aggregate for its suitability in concrete making and study the strength and behaviour of recycled aggregate concrete using three different types of demolition wastes, viz., concrete, wire-cut brick masonry and table-moulded (country) brick masonry. The compressive strength of recycled aggregate concrete is relatively lower and the variation depends on the strength of parent concrete from which the aggregates have been obtained. The range of compressive strengths obtained shows that recycled concrete of different mixes made with recycled aggregates obtained from i) demolished brick masonry can be used for manufacture of load bearing masonry units and plain cement concrete (PCC) works, and ii) demolished concrete aggregates can be used for both PCC and reinforced concrete (RC) construction.
