【摘要】 透水性混凝土与普通混凝土不同,由于含有大量的连通孔隙使强度变得很低。所以,如何提高强度是透水性混凝土的关键技术之一。本文用改变骨料级配的方法研究了透水性混凝土的强度、超声波速度与孔隙率之间的关系。更多还原

【Abstract】 Different from the ordinary concrete,the strength of porous concrete decreases remarkably with the continous void ratio.Therefore,how to increase the strength of porous concrete is of great importance.By the method of aggregate mixing ratio,the physical and mechanical performance of porous concrete is described,and the relation between the ultrosonnic velocity method and the porous ratio is also given.更多还原
