Abstract:
This paper reports an experimental investigation to evaluate the performance of reinforced concrete slabs made with shrinkage compensating concrete. The effects of type of cement, type ofaggregate, percentage and position of reinforcement, slab thickness and curing conditions on expansion and subsequent shrinkage were evaluated. Measurements were made on 41 slabs. Flexural tests were conducted to determine the effects of the variables on cracking and strength. Generally, the level of expansion affected the cracking loads but had no effect on flexural strength. Final net shrinkage for slabs with shrinkage-compensating concrete was less than that for comparable slabs made with Type I cement. Creep tests were also conducted to measure the properties of shrinkage compensating concretes under constant axial load. The results were compared with data from similar specimens containing Type I cement. Initial deformations were predicted accurately usin the theory of elasticity. Measured creep of the slabs containing shrinkage-compensating concretes was higher than the creep of corresponding Type I slabs.

In Japan, expansive cement concretes are made by the addition of expansive components at the time of mixing in the field. According to the quantity involved these expansive components can be used in shrinkage-compensating concretes, or self-stressing concretes. This paper describes the present state of expansive cement concretes in Japan, some information on principal research reports, standard test methods, recommended practices, and examples of the use of expansive cement concretes for various types of structure.

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 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.
