Rubber concrete: Mechanical and dynamical properties

2018-12-1  Topcu [ 9] has examined the physical and mechanical properties of rubberized concretes with initial compressive strength of 20 MPa. The amounts of the rubber used in the rubberized concrete were15%, 30%, and 45% by volume of the total aggregates. This study has concluded that a general reduction in the compressive strength of rubberized ...
