Autogenous Accelerated Curing of Concrete Cylinders

Report No: 70-R28

Published in 1971

About the report:

Eighteen different concrete mixtures were proportioned to investigate the influence of cement types (II and III), water cement ratios (0.4, 0.5, and 0.6), and admixtures (accelerator, retarder, and air entraining agent) on the moisture changes during autogenous curing of concrete cylinders. A total of 360 concrete cylinders were made comprising autogenously cured cylinders, 28-day, 91-day, and 1 year moist cured cylinders, and autogenously cured cylinders instrumented for moisture and temperature measurements. In addition to measurements of moisture movement and temperature development routine tests for slump, unit weight, air content, and compressive strengths were made. This report describes the influence of concrete mixture variables on the movement of moisture, the rate of water fixation, and the total quantity of water fixed during autogenous accelerated curing; and the relationships among the moisture parameters resulting from the measurements. The relationships between the moisture and temperature parameters are also presented. The report lists nine observations and conclusions.
