摘要
为促进固废材料的资源化利用,研究采用固废材料全替代水泥并掺加不同掺量的纳米SiO2和纳米CaCO3制备纳米固废混凝土,进行纳米固废混凝土的抗折强度试验和弯曲疲劳试验.试验结果表明,纳米材料可以增强固废混凝土的抗折强度并改善其弯曲疲劳性能,纳米SiO2和纳米CaCO3分别在掺量为2%和1%时对固废混凝土的抗折强度和疲劳性能的改善效果最显著.研究可为固废混凝土在道路、桥梁以及港口码头等交通基础设施中的推广应用提供理论依据.
Abstract
To promote the resource utilization of solid waste materials,nano solid waste concrete is prepared by re-placing cement with solid waste materials and adding nano-SiO2 and nano-CaCO3 with different amounts.The flexur-al strength and flexural fatigue of nano solid waste concrete are investigated.The results show that nanomaterials en-hance the flexural strength and improve the flexural fatigue properties of solid waste concrete,and nano-SiO2 and na-no-CaCO3 have the most significant effectiveness on the flexural strength and flexural fatigue properties of solid waste concrete when the content is 2%and 1%,respectively.
