The effects of common cement types in Guizhou on mortar shrinkage properties and pore structure parameters were explored, providing experimental reference for the rational selection of cement. Based on this, four kinds of common cement (Haolong cement, south west cement, Yaobai cement, Zhongcheng cement) in Guizhou were used to investigate the mechanical properties, shrinkage performance and pore structure parameters of mortar. Results show that with the extension of curing age, the flexural strength and compressive strength of mortar increase, but the difference in the compressive strength of four cement mortar at 90d is less than 3MPa. The compressive strength and flexural strength of mortar show a significant linear relationship, and the folding and pressing ratio shows a decreasing trend. Drying shrinkage and autogenous shrinkage of cement mortar both increase with the extension of curing age , but the drying shrinkage is always higher than that of autogenous shrinkage. Through the water-absorbing method it can be found that the prolongation of the curing age had a refinement effect on the homogeneity of the mortar pore structure, but the average pore diameters of the four cement mortars were not significantly different and the difference is less than 0.04. Based on the above findings, it can be concluded that the performance of cement varies as the cement producing area varies also, it is suggested that the choice of 4 kinds of cement follows the order: southwest cement>Zhongcheng cement>Yaobai cement>Haolong cement.
