May 17, 20180183;32;C7/8 / Gen 0. C7 8 concrete mix, Gen 0 concrete or wet lean mix concrete, is commonly used in both commercial and domestic projects for a huge range of general applications, such as kerb bedding, haunching and backing, domestic foundations and blinding.

If the load gets large enough, the concrete will fracture and be crushed. The crush strength is the load (similarly measured) at which a slab of specified thickness will begin to show breakup and crushing. There is a spread between these measures. Compressive strength of a particular concrete mix might be, say, 6000 pounds.
