The future of expansive cement depends on a realization by cement users that there are circumstances where the best cement to use is one that expands. If there is an awareness that it is the optimum product for certain uses then it will be made available and its future will be assured.

Joe V. Williams, Jr.
A brief description of the scope of shrinkage-compensating usage in various types of hydraulic structures is given. Effects of shrinkage-compensating concrete on reduction of drying shrinkage stresses, cracking, and water stops as potential points of leakage are discussed. Design considerations by some engineering firms with respect to shrinkage reduction, particularly in circular tanks, are outlined. Construction advantages, such as higher slumps, ease of placement, reduced honeycombing ,and larger placement areas are covered. Durability factors such as freezing and thawing, deicer scaling, abrasion, and sulfate exposure are compared with portland cement concretes.

Charles A. Gaskill and Richard C. Jacobs
Expansive concrete has been used in a variety of warehouse applications but not under multiple temperature conditions. In addition, job data to support degrees of shrinkage compensation has been limited. This project was used to compare slab design theory with on-site analysis of concrete expansion and shrinkage. Measurement pins were placed at 50 ft (15.24 m) and 100 ft (30.48 m) intervals and arranged to measure center and edge slab movement under a variety of restraint and temperature conditions.

A description of the role of the architect, engineer, laboratory, and contractor in the design and construction of this all cast-in-place concrete structure is given. Di scusses shrinkage control to reduce cracking, and the dual role played by shrinkage-compensating concrete and post-tensioning in achieving this. Explains field, as well as laboratory, testing of concrete to determine effect and amount of expansion experienced.
