水泥土无侧限抗压强度的试验研究

分析了土的塑性、水泥和外加剂掺量对水泥无侧限抗压强度的影响。试验结果表明,水泥土无侧限抗压强度随土的塑限增大而先减小后增大,随着水泥掺量的增加,水泥土无侧限抗压强度有明显增长,掺了减水剂的水泥土的7 d强度有所增加,但以后强度几乎没有增长。

Research on experiment of concrete unconfined compressive strength

The paper analyzes the influence of the soil＇s plasticity,and the mixture of the concrete and admixture on the unconfined compressive strength,proves by the experiment results that the concrete＇s unconfined compressive strength increases along with the soil＇s reducing plasticity,and the concrete＇s unconfined compressive strength can obviously increases when the mixture of concrete is added,and the 7 d strength can increase by mixing the water-reducing agent,but later the strength will not increase.
