Learn MoreBatching and Mixing. Batching-- Batching of aggregates and cement should always be done by weight. Other components, like water and admixtures, can be batched by volume. Batching by weight allows rapid and convenient adjustment of mix parameters if desired. Material quantities should be measured with a high degree of accuracy.

Learn MoreBy using table 17-5 and interpolating between fineness moduli of 2.6 and 2.8, you find that for 3/4-inch aggregate having a fineness modulus of 2.7, the volume of dry-rodded aggregate per unit volume of concrete is 0.63. Therefore, the volume of coarse aggregate needed for 1 cubic yard of concrete is 0.63 x 27 = 17.01 cubic feet.
