摘　　要：通过对9个配合比的试验,研究了胶凝材料(水泥、黏土、膨润土)用量的变化对塑性混凝土轴心抗压强度的影响。结果表明:塑性混凝土轴心抗压强度随水泥用量增加而增加,随黏土用量增加而减小;水泥用量的影响小于黏土用量的影响;膨润土掺入对强度存在有利和不利两方面的影响。Based on the nine group mix proportions,this paper investigated the impact on the axial compressive strength of the plastic concrete and the influence mechanism of the content of the cementitious materials such as cement,clay and bentonite and influence mechanism.The results showed that：the axial compressive strength of plastic concrete increases with the cement content increasing and decrease with the clay content increasing;the influence of the cement content is more than that of the clay content;the add of the bentonite has both advantage and disadvantage influence on strength.
