This report deals with consideration in compressive strength and Young’s modulus of concrete on different slump in identical with water-cement ratio. This paper investigates mix-proportions of ready-mixed concrete, compressive strength and Young’s modulus for test piece of making production control of ready-mixed concrete. As a results, compressive strength show a tendency to get bigger when slump is bigger in identical with water-cement ratio. Young’s modulus show a tendency to get bigger when slump is smaller in identical with water-cement ratio.
