The shrinkage of cement paste during hardening is caused by chemical reactions of the clinker minerals with water during the first hours. At a later stage it is caused by changes in the water content of the hardened paste. Measurements of pulse velocity, volume shrinkage and heat of hydration on hardening portland cement support the idea that the formation of ettringite is an important link in the mechanism of shrinkage in the plastic state of cement paste and mortar. Mechanical tests on prisms of 4 x 4 x 16 cc gave some information about the difference in sensitivity to surface corrosion of different types of cement. This paper is an abstract from the report of the commission B10: "The influence of the shrinkage of cement on the shrinkage of concrete" of the Netherlands Committee for Concrete Research (CUR).
