分析了导致混凝土强度不足的原因。
首先，钢纤维和轻骨料能弥补普通混凝土存在的抗拉强度低和自重大等方面的不足。
First, the steel fiber reinforced concrete and the lightweight aggregate concrete can make up the deficiencies of common concrete such as low tensile strength and large dead weight.
某工业厂房现浇混凝土楼面由于混凝土抗压强度偏低和负弯距钢筋下移，造成了抗弯承载力不足，出现了大量裂缝。
The low grade of concrete and negative moment reinforcement descending cause the appearance of concrete crack in a workshop floor.
