摘要
通过扫描电镜、差热分析(DTA)、热重分析(TGA)及红外光谱对聚丙烯酰胺改性混凝土的微观结构及其与混凝土的物理化学作用进行了分析,并且讨论了聚丙烯酰胺对混凝土力学性能的改性效果与改性机理。结果表明聚丙烯酰胺对混凝土的性能具有明显的改善作用。
In this paper, the microstructure of polyacryamide modified concrete and the physicchemical reaction of polyacrylamide to concrete are analysed through scanning electron microscope, differential thermal analyses, thermogravimetric analyses and infrared spectrum, as well as the ameliorated effects and mechanism of polyacrylamide to mechaniacl properties of concrete are discussed. Relevant tests and analysis show that polyacrylamide can effectively improve the performance of concrete.
