Preparation method of concrete precast slab with good sound insulation effect
The invention discloses a preparation method of a concrete precast slab with a good sound insulation effect, which comprises the following steps: mixing various raw materials, uniformly stirring at a high speed, adjusting the stirring speed, slowly adding a graphene oxide/fullerene composite gel solution, and uniformly stirring; spraying a release agent on the surface of a mold, pouring the mixed raw materials into the prefabricated plate mold, starting a vibration device, vibrating, flattening a blank, and covering with a cover plate; and heating at 42-45 DEG C for 2.5-3 hours, standing at normal temperature for 5-5.5 hours after heating is finished, demolding and discharging. The concrete prefabricated slab with the good sound insulation effect is prepared from Portland cement, water, sodium chloride, recycled concrete particles, graphene oxide/fullerene composite gel liquid, a polycarboxylate superplasticizer and fly ash. The recycled concrete particles with different particle size gradients are matched with the graphene oxide/fullerene composite gel liquid, so that the concrete prefabricated slab with a good sound insulation effect is obtained.
本发明公开了一种隔音效果好的混凝土预制板的制备方法，包括以下步骤：将各种原料混合后，高速搅拌均匀，调整搅拌速度后缓慢加入氧化石墨烯/富勒烯复合凝胶液，搅拌均匀；在模具表面喷涂脱模剂，将混合好的原料浇筑到预制板模具中，启动振动装置，振动，收平坯体，盖好盖板；42‑45℃加热2.5‑3h，加热结束后常温静置5‑5.5h后脱模出料，即可。本发明的隔音效果好的混凝土预制板，由以下成分组成：硅酸盐水泥、水、氯化钠、回收混凝土微粒、氧化石墨烯/富勒烯复合凝胶液、聚羧酸减水剂和粉煤灰。本发明由于采用了不同粒径梯度的回收混凝土微粒与氧化石墨烯/富勒烯复合凝胶液相互配合，得到了隔音效果好的混凝土预制板。
