 The impact of MgO contained in clinker on the shrinkage, hydration of cement was investigated. Alite polymorph and periclase relative contents in industrious clinker and hydrates of cement were determined by X-ray diffraction and derivative thermogravimetry. The mortar shrinkage was measured. The results show that periclase content increases with the increase of MgO content. Periclase hydrates at a higher rate at early age, and the increase of cured temperature accelerates the hydration rate. The expansion of periclase can decrease the shrinkage and increase the expansion of cement cured in dry environment and in water, respectively. The hydrate of periclase becomes amorphous or hexagonal plates, concentrates near-by Ca(OH)2, and carbonates with Ca(OH)2 to form CaMg(CO3)2.
