This document explores the extensive use of this concrete in various types of construction to eliminate or minimize cracking caused by dry 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 practice necessary to ensure 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 concrete is also appended.
