Autogenous Accelerated Curing of Concrete Cylinders

Report No: 70-R27

Published in 1971

About the report:

Forty-eight different concrete mixes were designed to investigate the influence of cement types (II, III, and V), cement contents (450, 550, and 650 lb. per cu. yd.), water cement ratios (0.4, 0.5, and 0.6), admixtures (accelerator, retarder, and air entraining agent), and initial mixture temperatures (50°F, 70°F, and 90°F) on the temperature development of autogenous accelerated cured concrete cylinders. A total of 940 concrete cylinders were made incorporating autogenously cured cylinders, 28-day, 91- day, and 1 year moist cured cylinders, and autogenously cured cylinders instrumented for temperature and moisture measurements. The project involved routine testing for slump, unit weight, air content, time of set, and compressive strengths. Additional measurements of temperature development and moisture movement were made. This report describes the influence of concrete mixture variables and initial mixture temperatures on the temperatures developed during autogenous accelerated curing and the relationships among the temperature parameters resulting from the measurements. The report lists eleven observations and conclusions.
