On the other hand, through inhibted performances of concrete and mortar, the permeability refutations with different w / c, ages, admixture, and physics chemistry absorb regulation of different viscosity permeable liquid, the liquid - gas method is proved science and accuracy. because adopting with liquid - gas method it case clearer concrete permeability regulation. different concretes relativity is more exact and more efficiency and fixed quantity

The results showed that compressive strength of sand mixture was markedly raised by using the silane coupling agent which can improve the surface contact state between sand and the binder
試驗結果表明,硅烷偶聯劑可以改善黏結劑與砂粒表面的接觸狀態,極大地提高堿酚醛樹脂砂的黏結強度。
