1、强度和重量比值增大 1, the ratio of strength to weight increases 这是钢纤维混凝土具有优越经济性的重要标志。 This is an important symbol of the superior economy of steel fiber concrete. 2、具有较高的抗拉、抗弯、抗剪和抗扭强度 2. High tensile, bending, shear and torsion strength 钢纤维混凝土抗拉强度提高25%~50%,抗弯强度提高40%~80%,抗剪强度提高50%~100%。钢纤维混凝土由于抗拉、抗弯、抗剪强度高,能承受较大的围岩和土体的变形作用而保持良好的整体性。 The tensile strength of steel fiber concrete is increased by 25% ~ 50%, the bending strength is increased by 40% ~ 80%, and the shear strength is increased by 50% ~ 100%. Steel fiber reinforced concrete has good integrity due to its high tensile strength, high resistance to bending and shear strength, and can withstand the deformation of surrounding rock and soil. 3、具有卓越的抗冲击性能 3. Excellent impact resistance 材料抵抗冲击或震动荷载作用的性能,称为冲击韧性,钢纤维混凝土抗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。 Material performance, resistance to impact or vibration load is called the impact toughness and impact resistance of steel fiber reinforced concrete compressive toughness can be improved 2 ~ 7 times, impact bending and tensile toughness can be improved several times to dozens times. 4、收缩性能明显改善 4. The shrinkage performance was significantly improved 钢纤维混凝土较普通混凝土的收缩值降低7%~9%。 The shrinkage of steel fiber concrete is 7% ~ 9% lower than that of ordinary concrete. 5、抗疲劳性能显著提高 5. The anti-fatigue performance has been significantly improved 钢纤维混凝土的抗弯和抗压疲劳性能比普通混凝土都有较大改善。 The bending and anti-fatigue properties of steel fiber reinforced concrete are better than that of ordinary concrete. 当掺有1.5%钢纤维抗弯疲劳寿命为1×106次时,应力比为0.68,而普通混凝土仅为0.51;当掺有2%钢纤维混凝土抗压疲劳寿命达2×106次时,应力比为0.92,而普通混凝土仅为0.56。 The stress ratio was 0.68 while the normal concrete was 0.51. When the compressive fatigue life of 2 % steel fiber reinforced concrete was 2 x 106 times, the stress ratio was 0.92, while the ordinary concrete was 0.56. 由于钢纤维混凝土具有较高的抗拉强度、断裂韧性和抗疲劳等性能,因此,可用于承受动力荷载的机墩、抗震结构的框架节点等部位。 Due to the high tensile strength, fracture toughness and fatigue resistance of steel fiber concrete, it can be used to bear the dynamic load and the frame node of seismic structure.
