查询词典 steel reinforced concrete

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.

本文试验研究结果可归纳如下：钢纤维的加入能明显提高钢纤维轻骨料混凝土的抗拉强度和抗折强度；掺入钢纤维使钢纤维轻骨料混凝土的抗压强度有一定程度的提高，增长幅度不大，但抗压韧性却有很大改善，使钢纤维轻骨料混凝土裂而不散；钢纤维轻骨料混凝土的弹性模量随钢纤维体积率的增大有一定提高；泊松比受钢纤维的加入影响不大，规律性不明显。

It was found in a high-rise building structure after fire that large-area concrete spalled at the bottom of slabs reinforced with low-alloy deformed steel bars. Temperature field of slabs during fire was determined by the ultrasonic-rebound combined method, and post-fire mechanical performance of concrete and steel bars were inspected by drilled cores and intercepted steel bars respectively.
