     · The slump line shows that the workability of mixtures with 40% CS has improved remarkably by 150% [ 31 ]. However, concrete mixtures with higher than 60% replacement of sand result in considerably lower compressive strength for all ages, while workability of mixtures with CS is improved considerably.

    The result of this recipe, assuming that four parts of gravel are also included in the mix, is a C20rated concrete. Concrete is rated on a number system that indies how strong the mix is after it has cured for approximately a month. C20 concrete would be considered a mediumstrength concrete mix. Higher numbers indie a stronger concrete.
