混凝土生产需要到的原材料有:水泥、砂石、矿物掺合料、外加剂等。不同地区生产的原材料在性能上存在着差异,就是同一地区、不同厂家,甚至同一厂家不同时期生产的原材料的性能都会有变化。当混凝土搅拌站所用原材料性能发生突变时,仍按平常配比生产混凝土,会引发混凝土质量问题。近期特别策划将针对这方面做一系列的讨论,分别讨论由水泥、砂石、矿物掺合料、外加剂的性能突变引起的混凝土质量问题以及所采取的相应解决措施。本期讨论水泥。 Concrete raw materials needed to produce are: cement, sand, mineral admixtures, admixtures and so on. The performance of raw materials produced in different regions is different, that is, the same region, different manufacturers, and even the same manufacturer at different times the performance of raw materials will have changes. When the performance of raw materials used in concrete mixing plant mutation occurs, the usual proportion of concrete production, will lead to concrete quality problems. Recent special planning will be a series of discussions in this regard, were discussed by the cement, gravel, mineral admixtures, admixtures caused by sudden changes in the quality of concrete and the corresponding measures to be taken. This issue discusses cement.
