  Influence of Recycled Coarse Aggregate on Properties of Concrete

  By O. J. Ameh, U. E. Edike

  Abstract: This study focuses on the influence of recycled coarse aggregate (RCA) on properties of concrete. Five different mixtures of RCA replacement comprising 0, 25, 50, 75 and 100% RCA were used. It was found that workability, saturated bulk density, compressive strength and flexural strength decreases with increase in RCA content in concrete. 100% manually RCA concrete passed the 17 kN/m2 compressive strength limit generally acceptable for concrete work of non-high …
