Title: Alternate Heating And Cooling Of Mortar
Author(s): E. R. Dawley
Publication: Journal Proceedings
Appears on pages(s): 609-620
Abstract:The effect of alternate heating and cooling, in water, on the compressive strength, length and weight of 3 x 6-in. mortar cylinders is reported for seven different brands of cement and three mixes. The first few cycles caused a sharp decrease in compressive strength after which there was either no change or some increase. The lengths and weights of all specimens increased. A cement which had excellent resistance to freezing and thawing had the least resistance to heating and cooling. As the test progressed the surface of the specimens checked, then cracked, and ridges of calcium car-bonate formed on the cracks.
