钢纤维粉煤灰混凝土的研究现状及展望

Research present situation and prospects of the steel fiber reinforce fly ash concrete

钢纤维掺入到混凝土中能显著改善其抗拉、抗弯、抗冲击、抗疲劳性能,具有良好的阻裂限缩能力,并能大幅度提高混凝土的韧性;粉煤灰掺入到混凝土中能够减轻结构自重、增强抗震性、抗裂性、耐久性、耐火性,且粉煤灰的利用对保护环境有积极的影响,技术经济效益也有所提高。文中介绍了钢纤维粉煤灰混凝土的研究现状和应用情况,并对该新型复合材料的发展方向作了分析。

The steel fiber mixes into the concrete to remarkably improve its anti-pull, anti-curved, the anti-impact, the fatigue resistance energy, has the good anti-crack to limit shrink the ability, and can large scale enhance the concrete toughness; The fly ash mixes into the concrete to reduce the structure dead weight, enhance anti-knocking property, the crack resistance, the durability, the fire resistance, also the use of fly ash for protecting the environment have the positive influence, the technology economic efficiency also has the enhancement. This article introduced the steel fiber fly ash concrete re.arch present situation and the application situation, and have made the analysis to this new compound material development direction.
