粉煤灰-矿渣复合超细粉蒸养混凝土力学性能

研究了在蒸汽养护和标准养护条件下掺粉煤灰－矿渣复合超细粉蒸养混凝土的力学性能，试验结果表明：粉煤灰－矿渣复合超细粉的掺入改善了蒸养混凝土的力学性能，并使蒸养混凝土具有较大的后期强度增长度，与空白对比组的混凝土相比，粉煤灰－矿渣复合超细粉混凝土的干缩显著降低。

Experimental Study on Mechanical Properties of Steam Curing Concrete with Ultrafine Fly Ash-Slag Composite

At steam curing and moist curing conditions, the mechanical properties of concrete with different fineness and different proportions of ultrafine fly ash slag composite were studied. The experimental results indicate that the addition of ultrafine fly ash slag composite improves the long term mechanical properties of steam curing concrete. The concrete with ultrafine fly ash slag composite has lower drying shrinkage compared to that of control concrete.
