  • The effect of aggregate size on strength and deformation

    Increasing the granular composition of the aggregate increases the efficiency utilization of cement in concretes working in compression. At the same time there is a reduction in deformation and an increase in Young s modulus and unit weight of the concrete. The tensile strength of the concrete is severely affected by increasing the size of the aggregate. On increasing the maximum grain size
