Studies Of High-Pressure Steam Curing
J. C. Pearson and E. M. Brickett
Appears on pages(s):
An exploratory investigation of factors affecting strength of concrete containing siliceous aggregate and cured in high-pressure steam. Tests were made at gage pressures from 68 to 200 psi and for curing times from 12 to 66 hr. Longer curing at lower pressures and shorter curing at higher pressures gave similar results. Strengths were in general higher from l8-hr curing at 150 psi than from 28 days’ damp curing. Effects of type of cement and a gregate, b consistency, luantity of cement, and age efore steaming were a so investi-gated.
