Early-strength rapid-hardening conductive concrete and preparation method thereof
The invention discloses a preparation method of early-strength quick-hardening conductive concrete. The preparation method comprises the following steps: step S101, uniformly mixing and stirring sulphoaluminate clinker, gypsum and fly ash for later use to obtain a mixture; step S102, uniformly mixing the mixture obtained in the step S101 with ordinary silicate clinker and silicon powder to obtain a composite cementing material; step S103, mixing the water-soluble polyethylene glycol-methacrylic acid copolymer with water to obtain dispersion liquid of the water-soluble polyethylene glycol-methacrylic acid copolymer in the water; step S104, fully stirring fine aggregate, sand, a water reducing agent, an early-strength accelerator, the composite cementing material in the step S102 and the dispersion liquid in the step S103 to obtain a mixture; and S105, pouring the mixture obtained in the step S105 into a mold to prepare a sample, vibrating during ramming, curing in a standard curing box for 1 hour, and demolding. The concrete has the beneficial effects of long service life and high stability, and can adapt to severe environments such as strong acid, strong alkali and the like.
本发明公开了一种早强快硬导电型混凝土的制备方法，包括以下步骤：步骤S101：将硫铝酸盐熟料与石膏以及粉煤灰混合搅拌均匀备用得到混合料；步骤S102：将步骤S101中的混合料与普通硅酸盐熟料以及硅粉混合均匀得到复合胶凝材料；步骤S103：将水溶性聚乙二醇‑甲基丙烯酸共聚物和水混合得到水溶性聚乙二醇‑甲基丙烯酸共聚物在水中的分散液；步骤S104：将细骨料、砂、减水剂、早强速凝剂、步骤S102中的复合胶凝材料以及步骤S103中的分散液进行充分搅拌，得到拌合物；步骤S105：将步骤S105中的拌合物倒入模具中制样，捣时振荡后至于标准养护箱中养护1h然后脱模。本发明的有益效果是：该混凝土使用寿命长，稳定性高，能够适应强酸强碱等恶劣环境。
