  • In order to effectively measure the permeability coefficient of porous concrete, the physical foundation of its permeability coefficient was analyzed, an ascertaining method of Darcy law applicable range to porous concrete was put forward.According to the measurement principle of constant head permeability test, a simple and practicable constant head permeameter of porous concrete was developed on the basis of considering the factors of side wall leakage, sleeve dimension and piezometer location.Besides, the factors of test piece status and water were analyzed, the test operation and data processing method of porous concrete were proposed, and the permeability coefficients of different porous concretes were tested.Test result shows that porous concrete has fine drainage performance, its permeability coefficient is more than 10 cm·s-1; there is power exponent relationship between its permeability coefficient and effective porosity, their correlation coefficient is 0.9681.The result indicates that the method can test the permeability coefficient of porous concrete accurately and effectively.
