添加剂对脱硫石膏耐水性影响试验分析

The water-tolerant property experimental analys i s of add it i ves＇ effects on desulfurizat ion gypsum

在大量实验的基础上，研究了矿物掺合料、缓凝剂、玻璃纤维对脱硫石膏耐水性的影响，通过调整矿物掺合料、缓凝剂、玻璃纤维的掺入量，获得了各添加剂对脱硫石膏的耐水性影响规律，进而为提高脱硫石膏的耐水性提供了合理的设计思路，为工程应用提供了理论依据。

The water-tolerant property of desulfurization gypsum was studied in this article considering the effects of the mineral admixtures, retarder and glass fiber based on a large number of experiments. By adjusting the admixing amount of mineral admixtures, retarder and glass fiber, rules of different kinds of additives＇ effects on the water-tolerant property of desulfurization gypsum were obtained. A set of mixture ratio was also acquired which can largely improve the water-tolerant property of desulfurization gypsum block and provide theoretical basis for engineering application.
