CEM I is ground cement clinker with a proportion of a gypsum and anhydrite mix or an alternative sulfate source (the amount limited by the SO 3 content of the cement) and is allowed to contain up to 5% of a Minor Additional Constituent (MAC). A MAC is defined in EN 197 as, ‘Specially selected, inorganic natural mineral materials, inorganic mineral materials derived from the clinker process or constituents as

Optimization of gypsum and slag contents in blended

Increasing the gypsum and slag contents in the blended cements containing slag is conducive to promote its green degree. The blended cement was prepared by mixing slag, gypsum and Portland clinker. Contour maps were designed to determine the optimal proportion of slag, gypsum and clinker by comprehensive considerations of strength, expansion, hydration, microstructure and crystallization

To control the setting of the calcium aluminate phase in OPC (C 3 A) and avoid what is referred to as a flash set, gypsum is added to OPC clinker, usually during grinding. This sulphate phase reacts with the C 3 A

Without gypsum, however, the clinker of low alite and high tricalcium aluminate phase behaved as flash set, and in this case, the rate of hydration of tricalcium aluminate phase was as high as 30% in 3 minutes after the mixing with water. With the addition of gypsum this value was lowered to 20%, and the clinker became normal set.
