The results show that a longer expansionperiod and a better expansion could be achieved with the blast furnace slag as expansion agent.
结果表明,用钢渣做膨胀剂,膨胀龄期较长,膨胀状况良好。

The longer of expansionperiod, the smaller of dam center's maximum thermal stress; and the final residual thermal stress, which can benefit the concrete's anti-cracking quality.
膨胀期越长,坝中心温度应力最大值越小,最终残余温度应力越小,对坝体混凝土的抗裂性有利。

And that has been a period of expansion and of anchoring balance and higher frequencies.
