Understanding the hydration of dolomite in cementitious

Jun 01, 2018 The presence of dolomite renders limestone unsuitable for the production of clinker, as the dolomite will decompose in the rotary kiln to form periclase (MgO), which forms brucite (Mg(OH) 2) during the later stages of cement hydration. The formation of brucite from periclase is an expansive reaction and makes the cement unsound.
