Types of Cracking and Influencing Causes

•Concrete contracts about 6 x 10-6/ oF •(10 x 10-6/ oC) on cooling. (varies with volume and type of coarse aggregate) •The outside cools faster than the core so tensile stresses can cause cracks if the thermal gradient > 35 oF (20 C) •With bridge decks, the substructure is cool and similar gradients will induce transverse cracking
