为提高钢纤维混凝土的压拉性能,将磁化水技术应用到钢纤维混凝土中。对磁化水水流速度与钢纤维体积率进行正交试验,并制作标准试块进行压拉强度试验,研究磁化水对钢纤维混凝土压拉性能的影响。试验结果表明:磁化水能有效提高钢纤维混凝土的压拉强度,当磁场强度为285 m T,水流速度为2.1 m/s,钢纤维体积率为1.8%时,磁化水钢纤维混凝土的压拉强度与素混凝土相比,28天立方体抗压强度提高23.71%,劈裂抗拉强度提高43.63%。对磁化水增强钢纤维混凝土压拉性能机理进行分析可知,磁化水能通过提高混凝土压拉强度和改善钢纤维与混凝土间的界面粘结力,增强钢纤维混凝土的压拉性能。 To improve the tensile properties of steel fiber reinforced concrete, magnetized water technology is applied to steel fiber reinforced concrete. Magnetized water flow velocity and volume fraction of steel fiber were orthogonal test, and the standard test block was prepared for the tensile strength test to study the magnetized water on the steel fiber reinforced concrete tensile properties. The experimental results show that magnetized water can effectively increase the compressive strength of steel fiber reinforced concrete. When the magnetic field strength is 285 m T, the flow velocity is 2.1 m / s and the volume fraction of steel fiber is 1.8% Compared with plain concrete, the compressive strength of 28-day cube increased by 23.71% and the splitting tensile strength increased by 43.63%. Magnetized water can enhance the compressive tensile properties of steel fiber reinforced concrete by increasing the compressive tensile strength of concrete and improving the interfacial adhesion between steel fiber and concrete.
