Abstract.In order to study the influence of steel-inorganic fiber on the mechanical properties of lightweight aggregate concrete, test parameters including single ceramic fiber and basalt fiber with different dosage and mixed steel-basalt fiber and steel-ceramic fiber reinforced lightweight aggregate concrete specimens with different doping methods were designed, and compared with the non-fiber reference group. The test results show that the compressive strength of cube is improved most obviously by steel-basalt fiber, with the maximum increase of 14.5%. Adding 1.35kg/m3 basalt fiber can increase the flexural strength of lightweight aggregate concrete by 62.2%. Adding ceramic fiber reduces the compressive strength of lightweight aggregate concrete, but improves the flexural strength.
