They also show that water absorption could availably evaluate the waterproof ability and resistance to acid and alkali corrosion of concrete protective coatings.

研究还表明吸水率可以有效评价混凝土保护涂层的防水能力和抵抗酸、碱侵蚀的能力。

The levels of water absorption, thermal shock, frost resistance, resistance of chemical etching, resistance to staining and luster are higher than any normal micro-powder tiles.

在吸水率，耐热，耐寒，抗腐蚀和防污性能方面的指标都比普通厂家微粉砖要高。

And the original volumetric water absorption can be regarded as a criteria to evaluate the resistance of concrete to salt physical attack.

可以以初始体积吸水率作为衡量混凝土耐蚀能力的标准，降低初始体积吸水率可以提高混凝土的耐蚀能力。
