摘要

为揭示原料尺寸对水泥增强用氧化石墨烯 (graphene oxide, GO) 结构-性能的影响, 本文以不同粒径的天然鳞片石墨为原料, 通过Hummers法制备出氧化石墨烯GO, 采用扫描电镜、X射线衍射、拉曼光谱、红外光谱等技术手段对氧化石墨烯的微观结构进行细致表征, 进而考察了原料粒径和氧化石墨烯GO掺量对其水泥早强效果的影响。实验结果表明, 随着原料粒径的减小, 氧化石墨烯GO产物层间距基本相同, 但氧化程度有所提高, 表面含氧基团增多; 在相同GO掺量情况下, 水泥胶砂试块的3d抗压、抗折强度随原料粒径的减小均呈先增后减的趋势, 原料粒径为13μm时GO产物对水泥早期力学强度的改善效果最佳; 在原料粒径同为13μm的情况下, 水泥胶砂试块的3d力学强度随GO掺量的提高而有所增大, 在GO掺量为0. 05%左右时抗压、抗折强度提升幅度分别为8. 85%和6. 34%, 效果较为显著, 但GO 掺量继续增大反而导致水泥胶砂强度下降。

Abstract

With the purpose of exploring the influence of raw material size on the structure-performance of graphene oxide (GO) for cement reinforcement, this paper used natural flaked graphite with different particle sizes as raw material to prepare GO nanosheets by a method of enhanced Hummers, and then used scanning electron microscope (SEM) , X-ray diffraction (XRD) , Raman spectrum, infrared spectrum (IR) and other means to characterise the microstructure of GO products in detail, and then investigated the effects of raw material size and graphene oxide GO dosage on its early strengthening effect in cement. The experimental results showed that with the decrease of raw material particle size, the spacing between the layers of GO products is basically the same, while the oxidization degree is increased, and the oxygen-containing groups on the surface are increased. When the GO matt was used to prepare cement mortar with same GO extent, the mechanical strengths at an age of 3 days were found to initially increase and then decrease with the reduction of raw material particle size, and the GO products had the best effect on the improvement of early mechanical strength of cement when the raw material particle size was 13μm. On the other hand, GO matt being obtained from the raw material particles in a size of 13μm was employed to prepare cement mortar with different GO content, of which the 3d strength was found to increase apparently with the increasing GO content, and thus resulted in the increment of 8. 85% to the 3d compressive strength and 6. 34% to the 3d flexural strength for the mortar specimen obtained with a GO content of about 0. 05%, but the further increasing of the GO content is not proposed, which might gave rise of a relative low mechanical strength.
