A Study of Durability in Temperature Cycles and Water Resistance of Sulfur Concretes and Mortars
The durability of sulfur concretes and mortars in expected-use environments is considered. The effects of temperature cycling and immersion in water are considered separately, and the effects of temperature, specimen size, and mold material on the strength of these materials are also discussed. The problem of biological attack is not considered. Immersion in water of specimens containing swelling clays can cause disintegration of sulfur concretes and mortars in a short time. Attempts to solve the problem caused by the presence of swelling clay are described. Partial success was obtained. The results of independent tests on the effects of water and temperature cycling should be considered before the result of freezethaw tests on sulfur concretes and mortars are interpreted. Erratum to this paper appear in 6(2).
