摘要
钢纤维增强聚合物矿物复合材料(SFPMC)中,聚合物基体、钢纤维、骨料和填料组成多相界面,利用KH-550偶联剂改善界面结合状态,进而提高材料力学性能。选取不同长径比和含量的钢纤维制备SFPMC,研究了经过KH-550表面偶联处理和未经KH-550表面偶联处理的钢纤维对聚合物矿物复合材料强度的影响,并分析了KH-550的偶联作用。试验结果表明:与采用未经偶联处理钢纤维的试件相比,采用经KH-550偶联处理钢纤维的试件抗压强度提高显著,最大抗压强度可达110.8MPa,比采用未经偶联处理钢纤维的试件提高了13.68%。
The multiphase interface of steel fiber reinforced polymer concrete （SFPMC） which is composed of polymer, steel fiber, aggregate and filler can be meliorated by using KH-550, so the strength of SFPMC is improved. SFPMC was fabricated by using steel fiber with different amount and rate of length and diameter. The coupling effect of KH- 550 was discussed. The result shows that steel fiber which applies coupling treatment Of KH-550 has greater reinforcement on compressive strength of SFPC than that which does not applies coupling treatment. The greatest compressive strength of SFPC which applies with coupling treatment reaches 110.8MPa, higher 13.68 % than that do not apply coupling treatment .
