引气混凝土 meaning in English
air-entrained concrete
air-entraining concrete
Examples
- However , the frost resistance of air entraining concrete decrease after adding salts
而引气混凝土中掺盐后抗盐冻剥蚀能力均有所下降。 - The abrasion resistance of air entraining concrete has little changes when salts added into concrete
引气混凝土中掺盐后耐磨性基本不变。 - The problem of the reinforcement corrosion has already drawn the wide attention of the academic circles , and has been conducted the massive research . however the reinforcement corrosion of air - entrained concrete has not been taken into the systematic research
国内外学者对普通钢筋混凝土进行了大量研究,得出了很多重要的结论,但对引气混凝土的抗钢筋锈蚀性能研究则较少。 - The result indicates that when the air content of the concrete changes from 1 to 4 percent , the polarized resistance of the identical flow electricity time increases along with the increment of the air content , the corrosion current density reduces along with the increment of air content , the chloride ion diffusion coefficient reduces with the increment of air content ; when air content changes from 4 to 6 percent , the rule of the change of the polarized resistance and corrosion current density happens to be the opposite , the diffusion coefficient of the chloride ion increases along with the increment of air content ; when the air content is 4 percent , the rust - resisting property of concrete is best , and so is the impermeability of the concrete
试验结果表明,混凝土的含气量在1 . 9 % ~ 4 . 2 %变化时,极化电阻随含气量的增大而增大,腐蚀电流密度随含气量的增大而减小, cl -扩散系数随含气量的增大而减小;当含气量在4 . 2 % ~ 6 . 4 %变化时,极化电阻、腐蚀电流密度和cl -扩散系数的变化规律则相反;当含气量为4 . 2 %时,抗钢筋锈蚀性能最佳,抗渗性最好。 cl -扩散系数与钢筋锈蚀参数在一定程度上有着良好的相关性,抗渗性的结果较好地反映了混凝土中钢筋锈蚀的程度,可以用cl -扩散系数评价引气混凝土的抗钢筋锈蚀性能。 - 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
Na _ 2so _ 4掺入后,引气混凝土的氯离子扩散系数增大,抗渗性降低;而nano _ 2和nacl能够细化水泥石的孔结构,对混凝土的抗渗性有利,但提高幅度不大。
