The experimental results are summarized as follows: the tensile strengh and bending strengh of steel fiber reinforced lightweight aggregate concrete can be improved significantly by the addition of steel fiber; to some extent ,the addition of steel fiber can also increase the compressive strength ,although little , it radically improves the compressive toughness , and the steel fiber reinforced lightweight aggregate concrete will not fall apart with cracks; with the increase of the volume fraction of steel fiber, the elastic modulus is also rising somewhat; Poisson's ratio is influenced little with the addition of the steel fiber and the effect regularity displays unconspicuously.
