摘　　要：对钢纤维膨胀混凝土抗压强度、抗拉强度、抗折强度及抗折韧性进行了试验研究 ,试验结果表明 :钢纤维和膨胀剂的联合作用 ,大大提高了混凝土的抗压强度、劈拉强度及抗折初裂强度 ,并在一定程度上提高了混凝土的极限抗折强度及抗折韧性 .A series of tests including compressive test, tension test, flexural test and flexural toughness test has been performed for steel fiber reinforced expansive concrete. The test results show that compression strength, split tensile strength, flexural initial cracking strength of concrete are evidently increased by the combing action of steel fiber and expansive agent; that the ultimate flexural strength and flexural toughness are increased too.

关 键 词：钢纤维膨胀混凝土 抗压强度 劈拉强度 抗折强度
