施工过程中水灰比变化对混凝土抗压强度影响程度分析及控制

Analysis of Influences Exercised by Different Cementwater Ratios over Compressive Strength & Control Measures of the Ratios

本文从水灰比变化对混凝土抗压强度的影响入手,分析了水泥用量不变时用水量变化的影响和用水量不变时水泥用量变化的影响,提出了施工过程中对水灰比实施控制的方法和步骤,解决了施工过程因水灰比变化时对混凝土抗压强度的影响问题。

The essay is mainly written to cope with the influences of cementwater ratios over the compres- sive strength of concrete.The author has analyzed the different results in the following two cases.1)wa- ter content’s influence on the compressive strength when cement content remains constant;2)cement con- tent’s influence on the compressive strength when water content remains constant,and has put forward steps and approaches to controlling the cementwater ratios so that the problems of influence on the com- pressive strength might be properly worked out during construction.
