This paper, a continuation of paper No. 30-36, presents results Portland-pozzolan of a cooperative investi ation cements to determine the effect of chemical composition, physical character, and proportion of pozzolan on the strength, volume change, resistance to sodium sulfate, and other properties of mortars and concretes. As compared with portland cements, Portland-pozzolan cements are generally more grindable, produce more plastic concretes exhibiting less water gain, generate less heat of hydration, and produce more impermeable concrete; but they generally require more water for workability and exhibit greater shrinkage upon drying. Portland-pozzolan cements of proper composition are suitable for hydraulic structures, mass concrete, structures exposed to aggressive waters, and general concrete construction where extreme drying conditions are not encountered.
