摘　　要：开展泥浆立方体抗压强度试验,以研究不同含量粗砂、石灰对泥浆立方体抗压强度的影响及其之间的相关关系,寻找不同掺合料的最优配合比,为土坯墙的建造改良和加固提供理论数据.试验结果表明:随着粗砂含量的增加,试块抗压强度呈现先增大后减小的趋势;掺和石灰对试块抗压强度略有提高,随石灰含量的增加,试块抗压强度变化不明显.泥浆抗压强度与掺合料之间呈良好的3次多项式关系.In order to study the influence of coarse sand and lime with different contents on the compressive strength of the mud cube and the correlation between them, the compressive strength test of the mud cube were carried out, and the optimal mixing ratio of different admixtures was found to provide theoretical data for the improvement and reinforcement of the adobe wall. The experimental results showed that the compressive strength of the specimen increased first and then decreases with the increase of coarse sand content. The com- pressive strength of the test block was slightly improved by adding lime. with the increase of lime content, the compressive strength of the test block had no obvious change. There was a good polynomial relationship be- tween the compressive strength of the slurry and the admixture.
