粉煤灰对UEA膨胀性能的影响

Effect of Fly Ash on Expansion Properties of Concrete Added with UEA

研究了不同掺灰量对UEA膨胀剂水泥砂浆和混凝土膨胀性能的影响。结果表明 ,原状灰对UEA膨胀剂的膨胀性能基本没有影响 ,而磨细灰则有较大的影响 ,掺灰量越大 ,影响越大。当磨细灰掺量超过 10 %时 。

In this paper , the effect of fly ash on expansion properties of mortar and concrete with the addition of UEA has been studied, and the resuts have shown that the original fly ash hardly has any effect on the expansion properties of mortar and concrete with the addition of UEA; while the milled fly ash has great effect on expansion properties of mortar and concrete with the addition of UEA, and that the more the milled fly ash is added, the greater the effect is. When the content of milled fly ash is over 10 percent on the expansion properties is weakened.
