研究了水泥-石灰石粉-矿粉复合胶凝材料体系的干燥收缩性能。试验结果得到了石灰石粉和矿粉对水泥基材料干缩变形的影响规律。水泥-石灰石粉复合胶凝材料的干缩值随石灰石粉掺量的增加呈现先增加后降低的趋势，石灰石粉掺量为10%时达到最大值；矿粉的掺入可有效改善水泥基胶凝材料的干缩性能，同时，也可明显减少水泥-石灰石粉复合胶凝材料的干缩变形。

Dry shrinkage properties of the cement-ground limestone-slag composite cementitious materials are studied in this paper. The influences of the ground limestone and slag on the dry shrinkage deformation of cement-based materials are explored. The drying shrinkage of the mortars increases first and decreases later with the increasing dosage of the ground limestone, and which reaches the maximum at the ground limestone content of 10%. The incorporation of slag pow-der can effectively improve the dry shrinkage of cement-based materials, meanwhile, it can also obviously decrease the dry shrinkage of cement-ground limestone composite cementitious materials.
