How Concrete is Made

Special techniques are used for curing concrete during extremely cold or hot weather to protect the concrete. The longer the concrete is kept moist, the stronger and more durable it will become. The rate of hardening depends upon the composition and fineness of the cement, the mix proportions, and the moisture and temperature conditions.

IIT Roorkee professor discovers life saving concrete

Thick radial cracks, 3 - 7 mm wide, originating from the impact location, developed across the target thickness and traversed over entire span leading to brittle failure. The number of cracks in almost all plain concrete targets was found to be four. The reinforced and prestressed concrete targets, however, did not experience any visible cracking.
