What Are Concrete Mixing Ratios?
Quick Answer

Water must be added slowly to the mixture with a slump test performed to determine when the concrete reaches the correct, workable consistency. A slump test consists of filling an inverted Styrofoam cup that has the bottom removed with the mixture. When the cup is removed and the material settles, it should be one-half to three-quarters as tall as the cup for proper workability.
