Abstract:
Statistically analyzes field strength data supplied by various organizations using the accelerated method of estimating 28-day strength of concrete. Briefly, the accelerated* method consists of initial standard moist-curing of test specimens for 24 hr, followed by boiling for 31/2 hr, and testing in compression I hr later. The analyses of the test data indicate that the accelerated test method under discussion is an excellent means for rapid strength determination of concrete, and its use by the concrete industry is recommended.
