随着人们对工业废渣作为混凝土矿物掺和料优异潜能认识的深入和积累,复合型掺和料越来越受到人们的关注。复合型掺和料就是将各种工业废渣(如钢渣,粉煤灰等),通过一定的工艺磨细、按照适当的比例复合,取代混凝土中的部分水泥。它利用了多种成分性能的超叠加效应,充分发挥其优良特性的组合效果,克服单一品种的性能缺陷,使掺和料性能更优越。在此讨论矿物掺合料对水泥冻融性能的影响,为开发“高强绿色混凝土”等课题的研究提供了参考。
With the deepening and accumulation of knowledge about the excellent potential of industrial waste slag as concrete mineral admixture, composite admixtures have drawn more and more attention. Composite admixture is a variety of industrial waste (such as steel slag, fly ash, etc.), through a certain process of grinding, in accordance with the appropriate proportion of composite, to replace part of the concrete cement. It takes advantage of the super-additive effect of various compositional properties and gives full play to its combined effect of excellent properties to overcome the performance defects of a single variety and make the blending material superior in performance. This article discusses the impact of mineral admixtures on the freeze-thaw properties of cement, which provides a reference for the development of “high strength green concrete” and other topics.
