A method for preparing a fiber-reinforced foamed concrete based on cow hair, comprising the following steps: in the first step, pretreating the raw cow hair; in the second step, mixing the pretreated cow hair in the first step with cement, fly ash, fine In the third step, add water to the dry material after the dry mixing in the second step and continue stirring; in the fourth step, add water to the dry material after the third step. Add a foaming agent to the slurry, stir it evenly, put it into a mold and let it stand for foaming and molding. The invention uses cow hair as a reinforcing material to prepare a fiber-reinforced foam concrete. Compared with ordinary foam insulation materials, this product solves the common problems of low strength and easy cracking of foam concrete to a certain extent. At the same time, cow hair is a solid waste produced in large quantities in the tanning industry. Reasonable recycling of it can not only save costs, but also alleviate the environmental burden caused by the accumulation of cow hair. |
