| Abstract: | The paper studies the influence of factors of water-cement ratio,amount of bentonite,amount of coal powder and sand ratio to the permeability performance of plastic concrete through orthogonal tests of plastic concrete.The outcomes show that a) the water-cement ratio is the key affecting factor.Properly reducing water-cement ratio in the design of mixture can increase the impermeability performance of plastic concrete;b) when the amount of bentonite and sand ratio keep 50% and 60% respectively,the impermeab... |
