REDUCING DRYING SHRINKAGE IN CONCRETE

The Constructor

Upon wetting, concrete tends to expand. This type of shrinkage is caused by the loss of moisture from the cement paste constituent, which can shrink by as much as 1% per unit length. Unfortunately, aggregate provides internal restraint that reduces the magnitude of this volume change to about 0.05%.
