搅拌方式对混凝土含气量及孔结构的影响
Effects of Mixing Method on Concrete Air Content and Pore Distribution
摘要
Abstract
We studied the influence of the position of vibratory source and the parameters of the vibration mixing on concrete air content.In addition, we compared it with the widely used air-entraining agent technology.The results indicate that appropriate vibration mixing method with proper combination of parameters can improve the air content of the concrete to reach the freeze protection required level as well.By adding air-entraining agent during the vibration mixing, we can obtain better result of air-entraining.What' s more, the influence of these two methods on meliorating the structure of concrete aperture have complementary advantages.Besides, vibration mixing method can also improve concrete strength and other performance.关键词
