Properties of concrete made with recycled coarse

2013-11-5  Demolition of old buildings has produced a large amount of waste material. In this paper, experiments were performed to design the mix proportion of concrete made with recycled coarse aggregate from waste brick, and the workability, mechanical performance, and durability of the concrete with different contents of recycled coarse aggregate have also been investigated.

New Mixture Proportioning Method for Concrete Made

New method of mixture proportioning is proposed for concrete made with coarse recycled concrete aggregates (RCA). The proposed method, dubbed the “equivalent mortar volume” method, is predicated on the fact that RCA is a two-phase material comprising mortar and natural aggregate; therefore, when proportioning a concrete mixture involving RCA, one must account
