Mechanical behavior of three generations of 100%

2014-8-29  It can be observed that the compressive strengths of concrete containing RCA1 and RCA2 were 35.9 MPa and 36.8 MPa at 56th day which were slightly lower than the natural coarse aggregate concrete (43.1 MPa). The compressive strength of RC2 was 2.5% higher at the age of 56th day than that of RC1 though the bulk density of RCA2 was lower.
