Gypsum Addition an overview ScienceDirect Topics

Most standards now allow up to 5% limestone in the basic Portland cement. Limestone grinds more easily than clinker and therefore, together with gypsum addition which also grinds more easily, provides a very fine material to fill in the spaces. The high surface area material then is no longer reactive clinker and many plants control the

Kevin A. Paine, in Lea's Chemistry of Cement and Concrete (Fifth Edition), 2019 7.6.1 Cement Composition. The components of cements which most influence shrinkage are the alkalis, C 3 A and sulfate; these parameters interact with the fineness of grinding of the cement. 25 In addition, an increase in C 3 A or alkalis increases the first-drying shrinkage; while this increase can be nullified by
