摘要
以废旧聚苯乙烯塑料为原材料 ,经过特殊的化学改性 ,合成出了一种含离子基团的水溶性改性废旧聚苯乙烯水泥减水剂 (SPS)。实验结果表明 ,该减水剂对水泥具有优良的减水率和增强性能。本文详细研究了该减水剂的综合性能。
A new modified water soluble waste polystyrene cement water reducing agent was synthesized from waste polystyrene plastic by way of special chemical modification. Experiments showed high water reduction for cement and high enhancement for concrete. Comprehensive properties and stability of this water reducing agent and ita adaptability to different cements were studied in details.
