Geopolymer concrete coating material and preparation method thereof
The invention belongs to the technical field of concrete, and particularly discloses a geopolymer concrete coating material. The foaming material is prepared from the following raw materials in percentage by weight: 17.13 percent to 19.65 percent of water, 11.20 percent to 13.02 percent of water glass, 31.73 percent to 51.59 percent of fly ash, 12.41 percent to 32.27 percent of metakaolin, 3.71 percent to 4.90 percent of a foaming agent, 0.20 percent to 0.41 percent of manganese dioxide and 0.01 percent to 0.03 percent of calcium stearate. The invention also discloses a preparation method of the geopolymer concrete coating material. The preparation method comprises the following steps: (1) weighing the raw materials according to the weight ratio; (2) uniformly mixing fly ash, metakaolin, manganese dioxide and calcium stearate; (3) adding water glass, and uniformly stirring; and (4) continuously stirring at a low speed, adding water while stirring, stirring for a certain time, adding a foaming agent, and quickly stirring for 20 seconds to obtain the geopolymer concrete coating material. The concrete has the characteristics of light weight, heat preservation, heat insulation and the like in use performance, the problems of corrosion of steel bars in concrete caused by carbonization and the like can be solved, and the durability of a concrete structure is further improved.
本发明属于混凝土技术领域，具体公开了一种地聚物混凝土涂层材料。其由如下重量百分比的原料制成：水17.13％～19.65％、水玻璃11.20％～13.02％、粉煤灰31.73％～51.59％、偏高岭土12.41％～32.27％、发泡剂3.71％～4.90％、二氧化锰0.20％～0.41％、硬脂酸钙0.01％～0.03％。本发明还公开了地聚物混凝土涂层材料的制备方法，包括以下步骤：(1)按照重量比称取各原料；(2)将粉煤灰、偏高岭土、二氧化锰和硬脂酸钙混合均匀；(3)加入水玻璃，搅拌均匀；(4)然后继续慢速搅拌，边搅拌边加水，搅拌一定时间后，加入发泡剂，快速搅拌20秒，得地聚物混凝土涂层材料。本发明在使用性能上具备轻质、保温、隔热等特点，且能减缓因碳化造成的混凝土内钢筋锈蚀等问题，进一步提高混凝土结构的耐久性。
