Properties of Concrete

When permitted to dry, concrete will shrink The primary factor influencing the amount of drying shrinkage is the water content of the freshly mixed concrete Two basic causes of cracks in concrete are 1 stress due to applied loads and 2 stress due to drying shrinkage, temperature changes, durability related distress, and restraint...
