氧化石墨烯对水泥基材料性能的影响
Effect of graphene oxide on properties of cement-based material
摘要
Abstract
This paper aims to improve the performance of cement-based materials.The study pre-pares geaphene oxide by improving Hummers method,and studying the effects of GO content on mechani-cal properties and frost resistance of cement mortar.The results show that GO can improve the compres-sive strength and flexural strength of cement mortar.With more GO content,the compressive and flexural strengths of the cement mortar initially rise and then decrease,and the improvement in flexural strength of the 3 d cement mortar is more obvious.An appropriate amount of GO can accelerate the hydration reac-tion of cement with no change in the types of hydration products.The minimum of the mass rate and the loss rate of the compressive strength of the cement mortar appears under the same freeze-thaw cycles with the content of GO by 0.04%.So under current experimental condition.the mechanical properties and frost resistance are best with the content of GO by 0.04%.关键词
