  • How coarse aggregate affects the mix design of concrete

    Oct 07, 2019· Coarse aggregate, such as crushed stone and gravel, occupies a large portion of a concrete mix but it also adds strength to the final concrete batch and reduces its water demand. The properties of the coarse aggregate, such as angularity and strength of the material, can affect the concrete in numerous other ways, which we will outline below.
