Aggregate mixing ratio influencing the strength and ultrasonic velocity of Porous Concrete

LI Yu-kun,ZHOU Fu-an,WANG Chun-sheng,PIAO Ying-mo(Dept.of Civil Engineering,College of Equipment and Materials,Liaodong University,Dandong 118003,Liaoning,China)  
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.
