Shrinkage-compensating concrete is used extensively in various types of construction to minimize cracking caused by drying shrinkage. Although its characteristics are in most respects similar to those of portland cement concrete, the materials, selecting of proportions, placement, and curing must be such that sufficient expansion is obtained to compensate for subsequent drying shrinkage.

This recommended practice sets forth the criteria and practices necessary to insure that expansion occurs at the time and in the amount required. In addition to a discussion of the basic principles, methods and details are given covering structural design, concrete mix proportioning, placement, finishing, and curing. A bibliography of the major references covering expansive cements and concretes is also appended.
