The invention discloses a test method for measuring plastic concrete permeability coefficient. Six test pieces are manufactured; butter is mixed with coal ash or cement at the mass ratio of 1:2-2.5 to prepare a sealing material for sealing the test pieces and a die trial. The water pressure of a permeameter is added to 0.2 MP once, constant pressure is kept for 6 hours, and the water seepage height is taken by ten moieties by splitting the test pieces. The relative permeability coefficient of the test piece is calculated according to the following formula: Kr=aDm2/2TH. The average value of the relative permeability coefficients of the six test pieces is the permeability coefficient of the plastic concrete. The invention fills the blank of the plastic concrete test method, and effectively overcomes the problem that the test result in the mix proportion design of the existing impermeable wall plastic concrete can not truly reflect the practical impermeable ability, thereby better matching ...
