Water in Concrete

The most important factor affecting the amount of drying shrinkage and the subsequent potential for cracking is the water content or the amount of water per cubic yard of concrete Step 9 Dig out 4 inches of the mud bottom Pour in a 1 inch layer of pea gravel and then cover that with a 3 inch layer of hydraulic cement This forms a mud slab which gives you a solid surface
