摘要:
通过对43组129个100mm×100 mm×100mm的混凝土立方体试件进行试验研究,以钢纤维体积率、混凝土强度等级和碳化龄期为变量,研究了不同体积率、不同强度等级的钢纤维混凝土在不同碳化龄期下弯折性能的变化规律,探讨了钢纤维对混凝土抗折强度的影响机理.试验结果表明,混凝土基体强度等级较高时,随着碳化龄期和钢纤维体积率的提高,碳化后混凝土弯折性能改善比较显著,对基体强度等级为C30、体积率分别为1.0%和2.0%的钢纤维混凝土碳化3 d、7 d、14 d、28 d后,相对抗折强度分别为0.98,1.11,0.91,1.21和0.92,1.24,1.23,1.39.
Abstract:
Through the experimental study of 43 groups of 129 concrete cubes of 100mm×100 mm × 100mm, the changes of bending properties of steel fiber concrete with different volume rates and different strength grades at different carbonization ages were studied, and the influence mechanism of steel fiber on the flexural strength of concrete was discussed. The test results show that when the strength grade of concrete matrix is high, with the increase of carbonization age and steel fiber volume rate, the bending performance of concrete after carbonization is significantly improved, and the relative flexural strength of steel fiber concrete with matrix strength grade C30 and volume rate of 1.0% and 2.0% carbonization for 3 d, 7 d, 14 d and 28 d, respectively, the relative flexural strength is 0.98, 1.11, 0.91, 1.21 and 0.92, 1.24, 1.23 and 1.39, respectively.
