摘要: 为了研究高吸水树脂(SAP)玄武岩纤维混凝土的力学性能,对不同玄武岩纤维长度(6 mm、18 mm、30 mm)、不同玄武岩纤维掺量(0.1%、0.2%、0.3%)以及不同SAP掺量(0.1%、0.2%、0.3%)的SAP玄武岩纤维混凝土进行了立方体抗压、劈裂抗拉、抗折试验。试验结果表明:掺入长为18 mm,掺量为0.1%的玄武岩纤维对混凝土抗压强度的提高效果较好,提高率为9.67%;掺入长为18 mm,掺量为0.2%的玄武岩纤维对混凝土抗拉、抗折性能的增强效果较为显著,相比于素混凝土分别提高了20.82%、18.04%。对于SAP玄武岩纤维混凝土,随着SAP掺量的增加,其抗压、抗拉、抗折强度均呈先上升后下降的趋势。基于试验数据,得出了玄武岩纤维的最佳长度、掺量以及SAP的最佳掺量。

Abstract: In order to study the mechanical properties of SAP basalt fiber concrete, cubic compressive, splitting tensile and flexural tests were carried out on SAP basalt fiber concrete with different basalt fiber length (6 mm, 18 mm, 30 mm), different basalt fiber content (0.1%, 0.2%, 0.3%) and different SAP content (0.1%, 0.2%, 0.3%). The test results show that the compressive strength of concrete is improved by adding basalt fibers with length of 18 mm and content of 0.1%, and the increase rate is 9.67%. The effect of adding basalt fibers with length of 18 mm and content of 0.2% on the tensile and flexural properties of concrete is remarkable, which is 20.82% and 18.04% higher than that of plain concrete, respectively. For SAP basalt fiber reinforced concrete, with the increase of SAP content, the compressive, tensile and flexural strength of SAP basalt fiber reinforced concrete increases first and then decreases. Based on the experimental data, the optimum length, content of basalt fiber and the optimum content of SAP were obtained.
