concrete ability

Self-compacting lightweight concrete appeared right after the year of 2000, which at the same time has the self-compacting capability of self-compacting concrete and the high specific strength attribute as well as the thermal insulation ability of lightweight concrete.

自密实轻骨料混凝土是一种2000年以后出现的新型高性能混凝土，同时具备自密实混凝土的自密实性能与轻骨料混凝土的高比强度属性以及保温性能。

Research on Improving the Ability of Concrete to Protect Reinforcing bar Using Double-admixing Method

双掺技术提高混凝土护筋性的研究

But because of concrete ability of anti-pull to stretch very weak, a mass concrete construction cause cracking will be unavoidable.

另外，由于混凝土的抗拉伸能力很弱，所以，大体积混凝土结构出现开裂就很难避免。

The experimental results indicate that, after 3-year immersion in tidal region, the depth of chloride ion penetration of the anti-seawater corrosion concrete is only 13%~ 25% of that of the ordinary concrete, which means better anti-chloride ion ability of the anti-seawater corrosion concrete.

实验结果表明，大掺量矿渣微粉抗海水腐蚀混凝土的抗氯离子侵蚀能力远优于普通混凝土，三年浸泡龄期时，其氯离子渗透深度只有普通混凝土的13%~25%；

The primary characteristic of self-compacting concrete is its workability, especially fluidity and segregation-resistance ability.

免振捣混凝土的首要特征是其优良的工作性能特别是流动性能和 抗 离析性能.
