A method of estimating distribution of expansive strains produced in members of rectangular cross section with reinforcing bars arranged in any manner based on measured values of standard uniaxially restrained specimens is proposed. This method adopts the hypothesis that work performed by expansive cement concrete on restraining reinforcement is a constant value regardless of quantity and method of arrangement of reinforcement, and is a convenient met which does not include constants such as modulus of elasticity and creep coefficient of expansive cement concrete. Errors between estimated and measured values are approximately 20% at maximum, and the accuracy may be said to be adequate for practical purposes.

The object of this research was to determine if the use of shrinkage-compensating concrete in bridge decks minimizes cracking and the subsequent spalling caused by rusting of the steel reinforcing. The simulated bridge deck specimens made with shrinkage-compensating cements did not crack, or had only a few cracks when compared to the specimens made with Type 1 cement. The rate of corrosion of the reinforcing was about the same for both of the found to be about 20 percent greater than that of the Type 1 concrete, but the chloride ion concentration was approximately the same at a given depth. The elimination of cracks by using shrinkage-compensating cement concrete will prevent the rapid corrosion of the reinforcement and subsequent spalling in a bridge that occurs at a crack, and extend the life of the deck before repairs are needed.

This report describes the use of shrinkage-compensating concrete for a spillway chute invert. The contractor elected to use the Type K expansive cement alternate in lieu of the conventional Type II portland cement. A study was made to evaluate compressive strengths for various water-cement ratios, slump loss, restrained expansion, modulus of elasticity, and freeze-thaw durability. Quality assurance testing at the project consisted of casting standard compressive strength specimens and restrained expansion prisms for each of the 18 panels. This use of shrinkage-compensating concrete provided an effective means of crack control for a spillway chute invert slab.

Reports on a field survey of over 100 projects including parking structures, slabs on ground, and miscellaneous installations that used shrinkage-compensating cement concrete. Fifty nine of the projects were rated on the effectiveness in reducing drying shrinkage cracks and it was concluded that, on average, the cement was very effective. Six years later seventeen of them were re-examined and it was found that the cement was still very effective. Cracks are plotted on several plan drawings. A number of the projects were inspected several times within a year to determine the rate and extent of cracking. Some causes of cracking due to drying shrinkage are discussed. Twelve projects of portland cement concrete were also reported.
