摘　　要：对比研究了单掺钢纤维(0、1%、2%、3%)和碳纤维(0、0.1%、0.2%、0.3%)对地聚物混凝土力学性能和抗冲击性能的影响,分析了试件的破坏形态及纤维作用机理。结果表明:随着碳纤维掺量的增加,试件的抗压强度、劈裂抗拉强度、抗折强度和抗冲击性能总体变化不大;随着钢纤维掺量的增加,试件的抗压强度和抗折强度增大,劈裂抗拉强度和抗冲击性能先提高后降低,最佳钢纤维掺量为2%。The effects of single addition of steel fiber(0,1%,2%,3%)and carbon fiber(0,0.1%,0.2%,0.3%)on the mechanical properties and impact resistance of geopolymer concrete were compared and studied,and the failure mode and fiber action mechanism of the specimen were analyzed.The results show that with the increase of carbon fiber content,the overall changes in compressive strength,splitting tensile strength,flexural strength,and impact resistance of the specimen are not significant.With the increase of steel fiber content,the compressive strength and flexural strength of the specimen increase,the splitting tensile strength and impact resistance first increase and then decrease,and the optimal steel fiber content is 2%.
