| 摘 要： | 简要评述了混凝土耐久性与孔隙率及渗透性的关系.通过采用纯酒精测试混凝土孔隙率;透氩气性能测试混凝土渗透性,并用Klinkenberg效应进行校正,试验研究了混凝土加热前后孔隙率及渗透性的变化.结果表明,混凝土受高温后,:孔隙率及渗透性明显增大,从而可证明其耐久性降低.

| Abstract: | The relationship between durability of concrete and its porosity and permeability is describd briefly.And the porosity and permeability of concrete are investigated before and after the concrete being heated to high temperatures,by using of pure ethanol to measure porosity and gas(argon) to measure permeability,which should be corrected by the Klinkenberg(or slippage) effect.The results show that,after being subjected to high temperatures,the porosity and permeability of concrete are inlarged,and the durability is decreased. |
