POM纤维增强轻型混凝土力学性能的试验研究
Experimental study on the mechanical properties of POM fiber reinforced lightweight concrete
摘要
Abstract
Polyoxymethylene(POM)fibers of varying lengths and mass fractions were incorporated into expanded polystyrene(EPS)lightweight concrete.The reinforcing mechanism of POM fibers in lightweight concrete was investigated through scanning electron microscopy(SEM)analysis.Based on compressive strength and splitting tensile strength tests,the optimal fiber length and mass fraction of POM fibers were analyzed.The results indicate that the addition of POM fibers reduces the slump of lightweight concrete paste.SEM analysis demonstrates that the interwoven and bridged POM fibers within the lightweight concrete matrix can constrain crack development,thereby enhancing its mechanical properties.The maximum compressive strength of lightweight concrete was achieved with a POM fiber length of 12 mm and a mass fraction of 0.9%.Meanwhile,the maximum splitting tensile strength was attained with a POM fiber length of 12 mm and a mass fraction of 1.2%.Compared with compressive strength,POM fibers have a more significant enhancement effect on the splitting tensile strength of lightweight concrete.关键词
