Graphene oxide and silica fume composite modified concrete and preparation method thereof
The invention relates to the technical field of novel materials for civil engineering, and discloses graphene oxide and silica fume composite modified concrete and a preparation method thereof.The preparation method comprises the following steps that a water reducing agent is added into water, stirring is conducted for the first time in a mechanical stirring mode, then GO is added into the solution, and stirring is conducted for the second time in a mechanical stirring mode; continuously stirring for the second time by adopting the mechanical stirring mode to obtain a solution A; during feeding, firstly adding the cement, the silica fume and the sand into a stirring pot, carrying out dry mixing, then adding the solution A, carrying out first stirring, and then adding the crushed stones, and carrying out second stirring; after stirring is completed, a slump test is conducted immediately, if the slump test is qualified, the mixture is loaded into a test mold brushed with a release agent, and after loading, the mixture is placed on a vibration table to be vibrated for 50 s or slurry is discharged from the surface; and performing standard curing or steam curing.
本发明涉及土木工程新型材料技术领域，且公开了一种氧化石墨烯与硅灰复合改性的混凝土及其制备方法，包括以下步骤：先将减水剂加入到水中，采用机械搅拌的方式进行第一次搅拌，然后将GO加入到此溶液中，继续采用机械搅拌的方式进行第二次搅拌，得到溶液A；在投料时先将水泥、硅灰和砂加入到搅拌锅中，干拌，而后加入A溶液后进行第一次搅拌，而后加入碎石进行第二次搅拌；搅拌完成后立即进行坍落度测试，若坍落度测试合格则将其装入已刷好脱模剂的试模内，装料后将其置于振动台上振动50s或表面出浆为止；进行标准养护或者蒸汽养护。
