WHAT ARE THE PROPERTIES OF CEMENT CONCRETE? -

Jul 24, 2014  The cement concrete possesses the following important properties: It possesses a high compressive strength. It is a corrosion resistance material and atmospheric agent has no appreciable effect on it. It hardens with age the process of hardening continues for a long time after the concrete has attained sufficient strength.
