| 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。 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%~100%。 3.具有卓越的抗冲击性能。材料抵抗冲击或震动荷载作用的性能,称为冲击韧性,在通常的纤维掺量下,冲击抗压韧性可提高2～7倍,冲击抗弯、抗拉等韧性可提高几倍到几十倍。 4.收缩性能明显改善。在通常的纤维掺量高,钢纤维混凝土较一般混凝土的压缩值下降7%～9%。 5.抗疲劳性能显著提高。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 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明显区别外,由于钢纤维混凝土抗裂性、整体性好,因此耐冻融性、耐热性、耐磨性、抗气蚀性和腐蚀性均有显著提高。 1. The ratio of strength and weight increases. This is an important symbol of the superior economy of steel fiber concrete. 2. High tensile, bending, shear and torsion strength. The tensile strength of the steel fiber is increased by 25% ~ 50%, the bending strength is increased by 40% ~ 80%, and the shear strength is increased by 50% ~ 100%. 3. Excellent impact resistance. Material performance, resistance to impact or vibration load is called the impact toughness, in the usual fiber content, the impact compressive toughness can be improved 2 ~ 7 times, impact bending and tensile toughness can be improved several times to dozens times. 4. The contractile performance improved significantly. In general, the compression value of steel fiber concrete is 7 % ~ 9 %. 5. Anti-fatigue performance has been significantly improved. The anti-bending and anti-fatigue properties of steel fiber reinforced concrete have a better performance than that of ordinary concrete. 6. Permeability in steel fiber concrete and there were no significant differences compared with ordinary concrete, due to the crack resistance of steel fiber reinforced concrete, integral sex is good, so the freeze-thaw resistance, heat resistance, abrasion resistance and cavitation resistance and corrosion resistance are improved significantly. |
