全世界用作混凝土外加剂的硅粉年消耗量约100000t,主要用在欧洲。这么多硅粉可供伴合大约4Mm~3混凝土。最初混凝土预拌厂是出于降低成本的目的,用硅粉做水泥的替代物。但到80年代,使用硅粉的着眼点就转为用来改善混凝土的特性,籍以提高其工作性能,例如强度和耐久性。 The world’s annual consumption of silica fume as concrete admixture is about 100000t, mainly used in Europe. So much silicon powder for about 4Mm ~ 3 with concrete. The initial concrete mixing plant is to reduce costs for the purpose of using silica fume cement instead. By the 1980s, however, the focus of using silicon powder shifted to improving the properties of concrete to improve its performance, such as strength and durability.
