火山灰矿碴硫酸盐水泥是以水淬矿碴、人工或天然火山灰、无水石膏及少量含熟石灰质碱性激发剂按一定此例混合磨细所得水硬性胶结材料。其生产流程如图1所示。根据国内有关单位的生产和我们的试验,其标号在250~#～700~#不等。可用于工农业基本建设中。它是工业废碴综合利用的产物,是一种无熟料水泥。生产工艺较为简单,与硅酸盐水泥生产相比,
The volcanic ash ore sulphate cement is a water-hardened ore, artificial or natural volcanic ash, anhydrite, and a small amount of alkaline calcinating agent containing hydrated caustic in accordance with certain examples. Its production process is shown in Figure 1. According to the production of the relevant domestic units and our tests, the labels range from 250~#~700~#. It can be used in the basic construction of industry and agriculture. It is a product of the comprehensive utilization of industrial wastes and is a cement without clinker. The production process is relatively simple compared with the production of Portland cement.
