  • The Effect of Coarse Aggregate on Fresh and Hardened

    The optimum coarse aggregate content depends on two parameters. The first parameter is the maximum size, where lower values of maximum size lead to increased possibility of using high coarse aggregate content. The second parameter is the shape of the coarse aggregate, whether it's crushed or rounded, where a higher content of rounded shape leads to
