塑性混凝土抗渗性能的研究

Research on impermeability of plastic concrete

采用水工混凝土抗渗仪法对塑性混凝土的渗透性能进行研究,分析了水胶比、粉煤灰用量、膨润土用量、水泥用量、砂率等对渗透性能的影响。结果表明:水胶比、膨润土掺量、水泥用量是影响塑性混凝土抗渗性能的主要因素,同时适量掺入粉煤灰能有效地提高塑性混凝土抗渗性能。

The impermeability of plastic concrete is analyzed in this experimental test based on hydraulic structuer concrete permeability instru- ment method.In this paper,the influences on the impermeability of plastic concrete by the factors about water-binder ratio,amount of fly ash,ben- tonite consumption,cement content,sand ratio was studied respectively.It is shown that the water-binder ratio,bentonite consumption and cement content are the major influencing factors to the impermeability of plastic concrete,and the performance of which is improved effectively by the adquate input of fly ash.
