What is better a HIGH SLUMP or a low slump?
This depends on the application and the design of the concrete mix. For normal concrete a moderate slump of 3″ to 5″ is desirable. High slump is desirable when the concrete must be placed around a high concentration of reinforcing steel (High slump should never be attained through the addition of water). Low slump is desirable when concrete is placed in large open forms, or when the form is placed on a slope. The concrete mix must be designed for these special applications. Always check with our Quality Control Department when you question your application.
