Graphene modification treatment method for lightweight aggregate concrete and graphene modified lightweight aggregate concrete
The invention relates to a graphene modification treatment method for lightweight aggregate concrete and graphene modified lightweight aggregate concrete, and the surface modification treatment method for the lightweight aggregate concrete comprises the following steps: cleaning the upper surface of a floor layer in a wall, and sweeping slurry after cleaning is completed; preparing lightweight aggregate which comprises the following components: cement, aggregate and water in a water-cement ratio of (0.45-0.6): 1; manufacturing mortar cakes on the upper surface of the floor layer in the wall subjected to mortar sweeping; pouring lightweight aggregate after the ash cake is made; the surface of the poured lightweight aggregate is flattened, so that cement in the lightweight aggregate rises, the process is before the initial setting state of the poured lightweight aggregate, and then the surface of the flattened lightweight aggregate is coated with a mixture of graphene dry powder and cement dry powder before the initial setting state; and after coating is completed, the surface is scraped, ground to be flat and polished. The graphene coating has the advantages that graphene precipitation, floating and layering cannot be caused, and the graphene coating can be in full contact connection with the surface of concrete, so that the performance of the concrete is effectively improved.
一种用于轻骨料混凝土的石墨烯改性处理方法及石墨烯改性轻骨料混凝土，轻骨料混凝土表面改性处理方法，包括：将墙内楼面层的上表面进行清洗，清洗完成后进行扫浆；配制轻骨料，轻骨料的成分包括水泥、骨料和水，其中水灰比为0.45‑0.6:1；在扫浆后的墙内楼面层的上表面进行灰饼制作；灰饼制作完成后灌注轻骨料；对灌注后的轻骨料表面抹平，使得其内的水泥上升，此过程在灌注的轻骨料初凝状态之前，然后在初凝状态前在上述抹平处理后的轻骨料表面涂覆石墨烯干粉和水泥干粉的混合料；涂覆完成后，对表面批刮磨平，磨光。本申请具有不会导致石墨烯析出、漂浮、分层，并且能与混凝土表面充分的接触连接，从而有效改善混凝土性能的优点。
