Properties of recycled aggregate and recycled aggregate concrete: effect of parent concrete
Abstract In the present investigation, an attempt was made to study the influence of the strength of parent concrete on the properties of recycled aggregates and recycled aggregate concrete. In this study, four grades of normal concrete mixes: M20, M25, M30, and M40 were considered as parent concrete to produce the recycled coarse aggregates and recycled aggregate concrete. Four recycled coarse aggregates viz. RCA20, RCA25, RCA30 and RCA40 were derived from M20, M25, M30, and M40 parent concretes, respectively. Two grades of recycled aggregate concretes viz. MR20 and MR30, each with two sets of RCA were also produced. MR20 was designed with RCA20 and RCA25 and similarly MR30 with RCA30 and RCA40. The properties such as compressive strength, split tensile strength, flexural strength and ultrasonic pulse velocity were studied. The experimental results indicate that the compressive strength of recycled aggregate concrete made with RCA obtained from the same grade of parent concrete is lower than the normal concrete, whereas the RAC made with RCA obtained from higher grade of parent concrete is quite comparable. The energy absorption of RAC under flexural load is more than the controlled concrete.
