摘要：采用N-羟甲基丙烯酰胺水溶液与粒径为0.08~0.10 mm的蛇纹石粉末制备了外加剂，研究了掺该外加剂的蛇纹石混凝土高温后的性能。结果表明：掺N-羟甲基丙烯酰胺蛇纹石粉末复合外加剂的蛇纹石混凝土具有良好的高温防辐射能力；N-羟甲基丙烯酰胺蛇纹石粉末复合外加剂对蛇纹石混凝土高温前后的轴心抗压强度均有提高作用，同时，还可以提高高温后力学性能的稳定性。 Abstract: An admixture was prepared using N-hydroxymethacrylamide aqueous solution and serpentine powder with a particle size of 0.08~0.10 mm, and the properties of serpentine concrete after high temperature were studied. The results indicate that the serpentine concrete mixed with N-hydroxymethylacrylamide serpentine powder composite admixture has good high-temperature radiation resistance. The N-hydroxymethylacrylamide serpentine powder composite admixture can improve the axial compressive strength of serpentine concrete before and after high temperature, and also enhance the stability of mechanical properties after high temperature.
