钢纤维混凝土端部的相互作用
由于钢纤维均布于混凝土基体中,能减缓因荷载在混凝土基体中所引起的细裂缝端部的应力集中,从而控制混凝土裂缝的扩展,提高混凝土的抗裂性.同时混凝土与钢纤维有很强的界面粘结力,当载荷作用时,使钢纤维作为一个整体抵抗荷载的作用,显着提高了混凝土原有的抗拉,抗弯强度和断裂延伸率;使结构的刚度及承载力性能也有所改善.钢纤维的损伤与破坏是非常复杂的,其断裂特性是与钢纤维在混凝土端部的相互作用密切相关的。
Because steel fibers are distributed in the concrete matrix, they can reduce the stress concentration at the end of cracks caused by loads in the concrete matrix, thus controlling the expansion of concrete cracks and improving the crack resistance of concrete. At the same time, concrete and steel fibers have strong interfacial bonding force. When loaded, the effect of steel fibers as a whole to resist loads significantly improves the original concrete. Tensile strength, flexural strength and elongation at break also improve the stiffness and bearing capacity of the structure. Damage and failure of steel fibers are very complex, and their fracture characteristics are closely related to the interaction of steel fibers at the end of concrete.
钢纤维的混凝土是经常用到的加固产品之一,效果也是很显著的。首先起到很好的支撑、保护。钢纤维抗拉、抗弯、抗剪强度高,能够保护山体护坡等工程的整体性在储水、防渗、输水管道工程中的应用,该产品具有较高的抗冲磨、抗气蚀能力,因此可用于溢洪道、消力池、闸底板等承受高速水流作用的部位。其次,还具有良好的耐腐蚀性能,在海水等腐蚀环境中同样能够使用。
Steel fiber reinforced concrete (SFRC) is one of the commonly used reinforcement products, and its effect is remarkable. First of all, it has good support and protection. Steel fiber has high tensile, bending choufangg.89ix.comchuwuqit.37ix.com.cnbiaozhiz.37ix.com.cnqima.37ix.com.cnchuwuqi.37ix.com.cn chuguo.37ix.com.cnand shear strength, which can protect the integrality of slope protection in water storage, seepage prevention and water pipeline engineering. The product has high anti-erosion and anti-cavitation ability, so it can be used in spillway, stilling pool, sluice floor and other parts which bear the action of high-speed water flow. Secondly, it also has good corrosion resistance and can be used in corrosive environment such as sea water.
