Abstract

The mechanical performance of recycled aggregate concrete RAC is investigated An experiment on the complete stressstrain curve under uniaxial compression loading of RAC is carried out The experimental results indicate that the peak stress peak strain secant modulus of the peak point and original point increase with the strength grade of RAC enhanced On the contrary the residual stress of RAC decreases with the strength grade enhancing and the failure of RAC is often broken at the interface between the recycled aggregate and the mortar matrix Finally the constitutive model of stressstrain model of RAC has been constituted and the results from the constitutive model of stressstrain meet the experiment results very well
