Also Know, how do you make concrete? To mix your own concrete for footings and piers, use 1 part Portland cement, 2 parts clean river sand, and 3 parts gravel (maximum of 1 inch diameter and specially washed for concrete mixing). Add clean water, a little at a time, as you mix. The concrete should be plastic, not runny.
