What is the purpose of adding dish soap when mixing concrete?
As I read from a book from the 60's, soap was added to cement plaster when finishing the inside of a pool to make the mixture waterproof , although it seems a bit strange the purpose of the soap additive is to force out bubbles in the concrete, making it more waterproof. From this I assume you may also add soap to concrete floors to help make them waterproof too. For the plaster mix the books states, 1 part cement to 3 parts sand. It specifies 1-1/2 quarts liquid soap to a sack of concrete (1 sack = 94 pounds). Hope this helps!
