Abstract:
Method for determining the original water content of concrete, at the time of hardening, is presented alon with the influence of time-temperature conditions of dehydration, character of aggregate, and age and exposure of concrete on the method. Conclusions drawn show that: (a) water content at the time of hardening can be determined satisfactorly, after saturation by a 24-hr immersion, by dehydration at 1100 F for 2 hr, (b) composition of aggregate may effect results if volatilization of aggregate constituents occurs, and © age and exposure conditions of concrete specimens do not appear to affect test results. Sample computations for age and aggregate series of tests are included in an appendix.
