不同减水剂对β型磷建筑石膏性能的影响
Different Water Reducing Agents on the Properties ofβ Type Building Phosphogypsum
摘要
Abstract
The effects of polycarboxylate superplasticizer and sulfonated melamine superplasticizer on the fluidity, water reducing rate, setting time and dry compression strength of β type building phosphogypsum were studied.At the same time, the nonlinear fitting of the best dry reducing strength of the best water reducing agent (polycarboxylic acid) was performed by software,the fitting results and experimental results were compared.The results show that polycarboxylic acid water reducing agent has obvious improvement on fluidity, setting time and dry compression strength of β type building phosphogypsum, and the water reducing effect is better;especially in setting time.Sulfonated melamine has a little influence on the performance of β type building gypsum.By fitting and experimental results,the dosage of 0.48% polycarboxylate superplasticizer is more suitable for the β type building phosphogypsum.关键词
