उदाहरण वाक्य

1. Air entraining concrete
2. Air entrained concrete
3. However , the frost resistance of air entraining concrete decrease after adding salts
4. The abrasion resistance of air entraining concrete has little changes when salts added into concrete
5. The influence of inorganic salts on mechanical performance of air entrainment concrete is similar with non - air entraining concrete . all those inorganic salts can improve the frost resistance of concrete except calcium nitrite
6. Mix mineral additive into concrete has great effect on the pore structure , especially the addition of sodium sulfate coarsening the pore structure enormously , and increase the total porosity . after mixing sodium sulfate , the chloride ion diffusion coefficient of air entraining concrete increased , impermeability reduced ; but mixing sodium nitrite and sodium chloride can
