以钢纤维作为改性材料,分别以0.5%、1.0%、1.5%的体积率掺入到不同橡胶掺量(5%、10%、15%、20%)的橡胶混凝土中,通过立方体抗压试验、轴心抗压试验和小梁抗折试验,研究了钢纤维改性橡胶混凝土的基本力学性能。试验结果表明:对较多橡胶掺量的橡胶混凝土,钢纤维的掺入对立方体抗压强度提高比较明显,对轴心抗压强度的提高不明显,对橡胶混凝土抗折强度和韧性有显著提高,并随钢纤维掺量增加而增大。
The steel fiber was used as modified material and mixed with 0.5%, 1.0% and 1.5% of the volume fraction of rubber concrete with different rubber contents (5%, 10%, 15% and 20% Test, axial compression test and trabecular bending test were carried out to study the basic mechanical properties of steel fiber modified rubber concrete. The test results show that the compressive strength of steel fiber blended with CFC increased more for rubber-reinforced concrete with more rubber content, while the compressive strength of the core did not increase obviously, and the flexural strength and toughness of rubber-reinforced concrete significantly increased , And increased with the increase of steel fiber content.
