A large amount of research has
been conducted on the mechanism of action of steel fibers and the basic
properties of steel fiber reinforced concrete, which can be summarized
as follows:
1.强度和重量比值增大。这是钢纤维混凝土具有优越经济性的重要标志西安货架。
1. The ratio of
strength to weight increases. This is an important symbol of the
superior economy of steel fiber reinforced concrete in Xi'an shelves.
2.具有较高的抗拉、抗弯、抗剪和抗扭强度。在混凝土中掺入适量钢纤维，其抗拉强度提高25%~50%，抗弯强度提高40%~80%，抗剪强度提高50%~。
2.
It has high tensile, bending, shear, and torsional strength. Adding an
appropriate amount of steel fiber to concrete can increase its tensile
strength by 25%~50%, flexural strength by 40%~80%, and shear strength by
50%~.
3.具有*的抗冲击性能。材料抵抗冲
3.
It has * impact resistance. The performance of materials in resisting
impact or vibration loads, known as impact toughness, can be improved by
2-7 times with the usual fiber content. The toughness of impact bending
and tensile can be increased by several to several tens of times.
4.收缩性能*改善。在通常的纤维掺量高，钢纤维厂家，钢纤维混凝土较一般混凝土的压缩值下降7%～9%。
4.
Improved shrinkage performance. In typical steel fiber manufacturers
with high fiber content, the compression value of steel fiber concrete
decreases by 7% to 9% compared to ordinary concrete.
5.性能显著提高。钢纤维混凝土的抗弯和抗压疲劳性能比普通混凝土皆有较大改良
5.
Significantly improved performance. The bending and compressive fatigue
properties of steel fiber reinforced concrete are significantly
improved compared to ordinary concrete
6.耐久性能显著提高。钢纤维混凝土除抗渗性能与普通混凝土相比没有*区别外，由于钢纤维混凝土抗裂性、整体性好，因此耐冻融性、耐热性、性、抗气蚀性和腐蚀性均有显著提高。如：掺有1.5%的钢纤维混凝土经150次冻融循环，其抗压和抗弯强度降低约20%，而其余条件相共的普通混凝土却降落60%以下，通过200次冻融循环，钢纤维混凝土试件仍坚持完整。
6.
Significantly improved durability. Steel fiber reinforced concrete has
no significant difference in impermeability compared to ordinary
concrete. Due to its good crack resistance and integrity, it has
significantly improved freeze-thaw resistance, heat resistance,
resistance to air corrosion, and corrosion resistance. For example,
after 150 freeze-thaw cycles, the compressive and flexural strength of
steel fiber reinforced concrete mixed with 1.5% decreased by about 20%,
while ordinary concrete with similar conditions decreased by less than
60%. After 200 freeze-thaw cycles, the steel fiber reinforced concrete
specimens remained intact.
