Open publisher page 8 citations

Abstract

This paper deals with the compressive strength of recycled aggregate concrete.The influence of recycled coarse aggregate contents on the compressive strength of concrete,the strength development with ages,the age factor and the applicability of 28d compressive strength equation of normal concrete were investigated.It was found that the compressive strength decreases with the increase of recycled coarse aggregates,the development of compressive strength for recycled aggregate concrete are similar to that of normal concrete but with small age factors,the 28d compressive strength equation of normal concrete can not be used for recycled aggregate concrete.The work conducted in this paper provides some basic knowledge regarding the use of recycled aggregate concrete in practical engineering.
