摘　　要：对以偏高岭土为主要掺合料的砂浆体积稳定性进行了分析,并结合混凝土耐久性原理进行了水泥胶砂的干缩试验来评定混凝土的干缩性能,研究不同掺合料配比下对水泥砂浆试件的膨胀的影响,从而确定了以偏高岭土为主要掺合料改善砂浆体积性能的效用,为混凝土开裂研究提供了依据。Metkaolin as the main admixtures volume stability of the mortar was analyzed, and combining the princi- pie of the durability of concrete, cement grinding the dry shrinkage test was conducted to assess the dry shrinkage of concrete performance, the different proportion of admixture of cement mortar specimens of the effect of inflation, so as to determine the metkaolin as the main admixtures to improve the effectiveness of mortar volume performance to provide the basis for concrete cracking research.
