摘　　要：采用粉煤灰陶粒和页岩陶粒两种轻骨料,配制成28 d抗压强度分别为58.9 MPa和64.6 MPa的高强轻骨料混凝土,并采用弓形钢纤维对这两种轻骨料混凝土增强试验。结果表明,随着钢纤维掺量的增加,这两种轻骨料混凝土的抗压、抗折及劈裂抗拉强度均有不同程度的提高,尤以劈裂抗拉强度的增幅最大。By adopting two lightweight aggregates, sintered fly ash aggregate and shale aggregate, two types of high strength lightweight aggregate concrete with the compressive strength 58.9 MPa and 64.6 MPa in 28 days are developed and a type of arch steel fiber is introduced to conduct test on them. The test results indicate that the compressive strength, bending strength, and splitting strength of these two types of lightweight aggregate concrete are all increased to some different degrees with increase of the admixture of steel fiber,and among them, especially with the increase of splitting strength as biggest.
