大掺量矿物掺合料在大体积混凝土中的应用

High Volume Mineral Admixtures in Mass Concrete

粉煤灰、矿粉是电力、冶金工业废料之一,粉煤灰、矿粉作为矿物掺合料加入到混凝土中,可以改善混凝土的各项物理力学性能以及耐久性。本文介绍了大掺量双掺矿粉和粉煤灰在东方之门底板混凝土中的配合比设计、温度计算和实际应用情况,探讨了合理利用掺合料不仅取得良好的技术经济效果,也符合绿色混凝土的发展方向。

Fly ash, slag is the power, metallurgy, one of industrial waste, fly ash, slag as a mineral admixture added to concrete can improve the physical and mechanical properties of concrete, and durability. This article describes the large-dosage pairs of mixed slag and fly ash concrete floor in the ＂Gate of the Orient＂ in the mix design, temperature calculation and actual application of the rational use of mineral admixtures is not only good technical and economic results, but also in line with the green concrete development.
