The objectives of this investigation were to gain a better understanding of the behavior of self-stressing reinforced concrete structures and to determine the economic savings possible with the effective use of expansive cement under practical construction conditions. This report is primarily concerned with the first of the above objectives although potential economic savings in beams is briefly discussed. This report describes the evaluation of expansive cements by means of free expansion of mortar bars, effects of longitudinal as well as lateral restraints on self-stress development and mechanical properties, effects of eccentrical restraints, and effects of different curing conditions. It also describes the structural behavior of self-stressed concrete members and the determination of economic savings possible with the effective use of expansive cement under practical construction conditions. The expansive cement evaluated was a blend of portland cement, calcium aluminate cement, and gypsum. The calcium aluminate cement contents were varied from 10 to 25 percent and the gypsum contents were in the range of 10 to 20 percent. Two expansive cements, giving a medium and a high amount of expansion were selected for the remainder of the investigation.
