EXPERIMENTAL STUDY O N THE SHEAR STRENGTH OF

aggregate, which is called recycled aggregate concrete (RAC). RAC can be used for land filling and gravel mining. Recycled aggregate is more advantageous as it has lower density, elastic modulus and higher water absorption. Firstly, the experimental study on recycled aggregate concrete (RAC) for the mechanical properties of were studied.
