钢纤维高强轻骨料混凝土研究

wo lightweight aggregates, sintered fly ash aggregate and shale aggregate are adopted to obtain two types of high strength lightweight aggregate concrete with the compressive strength 58.9MPa and 64.6MPa in 28 days, and moreover, a type of arch steel fiber is introduced to reinforce 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 in different degree with the increment of volumetric dosage of steel fiber, but the elevated extent of splitting strength is the biggest.
