Mechanical Properties of Steel Fiber Reinforced Lightweight Aggregate Concrete
Experiments were conducted to study the basic properties of steel fiber reinforced lightweight aggregate concrete (SFLAC) mixed with machine-made sand and expanded-shale. The effects of sand ratio and cement content on the cubic and axial compressive strengths, splitting and axial tensile strengths, flexural tensile strength as well as compressive and tensile elastic modulus of SFLAC are analyzed comparing with those of LAC in the same conditions. Data from the experiments shows that, the steel fiber has advantages to every mechanical properties of LAC especially to the tensile strengths, and also modifies the abruptness failure states of LAC into multi-cracked characteristics of SFLAC. The optimum mix proportion is suggested for getting better properties of SFLAC.
