Reports strength tests of concrete made with normal and high-early-strength cements stored at different temperatures. Water content, preliminary curing, and age at test varied. Gain in strength followmg a given initial treatment was dependent on the temperature of exposure. The importance of initial curing at a favorable temperature was clearly indicated. Subsequent warming of concrete exposed to temperatures of 50 and 33 F did not help later strengths much when no moisture was supplied. The tests also indicated the danger of placing concrete having a temperature less than 70 F when temperatures below freezing are likely to be encountered.
