防渗墙粘土混凝土配合比试验研究

粘土混凝土性能介于塑性混凝土和刚性混凝土之间,具有和易性好、早期强度低、后期强度增长快、抗渗性能好、低弹模和相对较高的强度等特点,是一种理想的防渗墙材料。本文结合山西省米家寨水库除险加固工程粘土混凝土防渗墙试验研究工作,对粘土混凝土原材料选用、配合比设计及其抗渗性能进行研究。

Test Study on the Mix Proportion of Clay Concrete for Cut-of Wall

With special propertiesof good workability,low compressive strength of early days,fast increasing of late compressive strength,good anti-seepage performance,low elasticity,comparatively high strength,and etc,clay concrete is really a ideal material of cut-off wall with properties between plastic concrete and rigid concrete.Based on the testing of clay concrete for cut-off wall of MiJiaZhai Reservoir,the selecting of materials,mix design methods and anti-seepage performance of clay concrete have been studied in this paper.
