在使用钢纤维混凝土时
在使用钢纤维混凝土时,我们会发现在钢纤维混凝土中有一些乱向散布的短纤维在其中,这是什么呢?这主要是为了阻碍混凝土内部微裂缝拓展和阻滞微观裂缝发作的作用。
When using steel fiber reinforced concrete, we will find some scattered
short fibers in steel fiber reinforced concrete. What is this? This is
mainly to hinder the expansion of micro-cracks in concrete and prevent
the occurrence of micro-cracks.
在受荷(拉、弯)前期,水泥基料与纤维一起承受外力,当混凝土开裂后,横跨裂缝的纤维变成外力的主要承受者。因此钢纤维混凝土与通常混凝土对比具有一系列优胜的物理和力学性能。
In the early stage of loading (tension and bending), cement base
material and fiber bear external force together. When concrete cracks,
the fibers across the cracks become the main bearers of external force.
Therefore, compared with ordinary concrete, steel fiber reinforced
concrete has a series of excellent physical and mechanical propertie
