摘要:
 再生混凝土是一种绿色混凝土,但是力学性能不如普通素混凝土(C),往再生混凝土(RC)中掺入钢钎维制成钢钎维再生混凝土是一种改性再生混凝土,可以提高RC的力学性能。本试验制备了36个150 mm×150 mm×150 mm的钢纤维再生混凝土(SFRC)标准试样用于抗压强度和劈裂抗拉强度试验,同时还制备了72个150 mm×150 mm×550 mm的小梁试样用于四点弯曲试验,研究钢钎维掺量对再生混凝土力学性能,并通过试验观察分析了各配合比试样的破坏形态。实验结果表明,随着钢纤维掺量的增加,再生混凝土的强度均呈先增加后降低的趋势,当钢纤维掺量为1.0%时,再生混凝土强度提高最大。同时钢纤维的掺入也增强了再生混凝土的韧性,并降低离散性。
Abstract:
 Recycled concrete is a kind of green concrete, but its mechanical properties are not as good as plain concrete (C). Adding steel to recycled concrete (RC) to make steel fiber recycled concrete is a modified recycled concrete that can improve the mechanical properties of RC. In this test, 36 standard specimens of steel fiber recycled concrete (SFRC) with dimensions of 150 mm×150 mm×150 mm were prepared for compressive strength and split tensile strength tests. At the same time, 72 specimens of 150 mm×150 mm×550 mm were prepared. The trabecular specimens were used for four-point bending test to study the effect of steel brazing steel content on the mechanical properties of recycled concrete, and through experimental observation and analysis of the failure morphology of each mix sample. The experimental results show that with the increase of the amount of steel fiber, the strength of recycled concrete increases first and then decreases. When the amount of steel fiber is 1.0%, the strength of recycled concrete increases the most. At the same time, the incorporation of steel fiber also enhances the toughness of recycled concrete and reduces dispersion.
