Since it takes only a small amount of reactive aggregate to cause deterioration of concrete due to the alkali-silicate reaction, vast deposits of aggregates throughout the world are in danger of being rejected as undesirable for use in concrete unles

The tricalcium aluminate present in portland cement is known to be effective for chloride removal and can thus provide protection against steel corrosion. Contradictions are found in the literature with regard to the minimum tricalcium aluminate cont

Coarse aggregate has a large influence on drying shrinkage which is one of the major causes of cracking in concrete structures. The stiffer an aggregate, the lower is the drying shinkage of concrete. Since it is not possible to alter the stiffness ch

The history of the commonly used performance tests for soundness of cement and the evolution of the autoclave test are reviewed. Hydration-expansion characteristics of cement compounds and the relationship between expansion and unsoundness are discus

The performance tests are either unsatisfactory or nonexistent with regard to evaluation of sulfate resistance and alkali-silica reactivity of both portland and blended portland cements. Investigations on development of accelerated laboratory tests w

The air contents of several concrete mixtures were measured while the material was in a plastic state, and the results were compared to corresponding values determined microscopically on the same hardened concretes. Two volumetric airmeters, a roller
