氧化石墨烯对再生混凝土材料耐久性的影响

Effect of Graphene Oxide on Durability of Recycled Concrete Materials

近年来,随着纳米科技的飞速发展,纳米材料凭借其体积效应、量子尺寸效应等,在各个领域都展现出良好的应用前景。但目前纳米材料在水泥基复合材料中的研究尚处在起步阶段,理论和实际应用方面都存在很多问题,尤其是纳米材料对水泥基复合材料物理、化学变化过程和微观结构的改善,以及对水泥基复合材料耐久性影响的机理等问题尚处在探索阶段。用再生骨料代替天然骨料生产的再生混凝土具有耐久性不高、强度低等缺陷,因此,为了进一步改善再生混凝土的耐久性,使其能更好地在工程中得到应用,本文将0%~0.06%不同剂量的氧化石墨烯掺入再生混凝土中,通过冻融循环试验研究了氧化石墨烯对再生混凝土耐久性的影响。

In recent years,with the rapid development of nanotechnology,it has shown good application prospects in various fields by virtue of its volume effect and quantum size effect.However,the research on nano-materials in cement-based materials is still in its infancy,and there are many problems in theory and practical application,especially the nano-materials for the physical and chemical changes of cement-based materials,the improvement of microstructure,and the cement-based materials.Problems such as the mechanism of durability impact are still in the exploration stage.In this paper,recycled concrete produced by reclaiming aggregate instead of natural aggregate has shortcomings such as low durability and low strength.Therefore,in order to further improve the durability of recycled concrete and promote its application in engineering,this paper studies the effect of graphene oxide on the durability of recycled concrete through freezing-thawing cycle test by adding 0%~0.06%different dozes of graphite oxide into recycled concrete.
