氧化石墨烯复合PVA纤维增强水泥基材料的力学性能及耐久性研究
Research on Mechanical Properties and Durability of Graphene Oxide Composite PVA Fiber Reinforced Cement-based Material
摘要
Abstract
In order to solve the problems of poor durability and brittleness of concrete,In this paper,the effect of graphene oxide(GO)blended with Polyvinyl alcohol(PVA)fiber on the durability of cement-based materials was studied.GO was prepared by Hummers method and the structure and properties of GO were characterized.The mechanical properties and durability of mortars with different mix ratio were tested and analyzed,and the modification mechanism of GO and PVA fibers on cement-based materials was analyzed by MIP(Mercury intrusion porosimetry)and SEM(scanning electron microscope).The results show that GO and PVA fiber can improve the mechanical properties and durability of cement-based materials.GO composite PVA fiber can significantly optimize the pore structure of cement-based materials,reduce porosity,improve the resistance to chloride ion penetration and reduce the shrinkage of cement-based materials.关键词
