Committee 710 was organized in 1935 to study the use of high-early-strength cements in concrete products manufacture. This is a progress report and covers laboratory and plant tests on effect of grading of aggregate, kind of aggregate, volume change and resistance to freezing and thawing as influenced by the type of cement. These tests indicate that for the method of curing used (3 days moist room, then air until test) 70.lb of high-early-strength cement gave compressive strengths higher than 94 lb of normal portland ce-ment at ages of 3 to 28 days.
