橡胶粉对塑性混凝土抗剪性能影响及在水库加固中的应用
Influence of Rubber Powder on Anti-shear Performance of Plastic Concrete and Its Application in Reservoir Reinforcement
摘要
Abstract
In order to improve the shear resistance of plastic concrete,the direct shear test was used to study the influence of different water binder ratio and different rubber powder content on the shear friction coefficient and cohesion.The results show that the shear friction coefficient of plastic concrete increases with the increase of rubber powder content,but the cohesion decreases.The cohesion of plastic concrete increases with the decrease of water binder ratio.Coordinated regulation of rubber powder and water binder ratio can improve the shear friction coefficient and cohesion of plastic concrete,enhance the anti-seepage effect of earth rock dam foundation and dam body,and ensure the safety and stability of the dam.关键词
