Five ways to make a DIY foam agent for concrete at home
The
cement foaming agent is the core material in foam concrete. Only good cement foaming agents can make high-performance foam concrete products. Today, I will share the family production method of cement foaming agents.
Five kinds of cement foaming agents are mainly introduced: magnesium oxychloride cement foaming agent, rosin soap cement foaming agent, egg yolk concrete cement foaming agent, concrete composite foaming agent, and engineering cement foaming agent.
1. Rosin soap cement foaming agent
Start to mix rosin and sodium carbonate, stir and heat; dissolve citric acid in water, put the above two mixtures into a heating container for mixing by heating and heat preservation, add water and stir evenly, Add the required amount of glutinous rice flour to the above-mentioned secondary mixture and stir, then add a small amount of shampoo or detergent. Compared with the existing technology, compound foaming is adopted to greatly improve the quality of commercial foam, and the inner wall of the bubble formed by foaming can also form a layer of extremely thin polymer crystal film with a waterproof function. Adding this cement foaming agent, The mortar has a better heat preservation function.
2. Concrete composite foaming agent: includes the following processes
1. Use an appropriate amount of soap powder; 2. A small amount of shower gel or shampoo; 3. Make some composite foaming agents; 4. Write the foamed foam into Mixed foam concrete mixture, then cast it into shape. After the foam concrete is added with the waterproof concrete composite foam agent prepared by the above method, it can overcome the shortcomings of its high water absorption rate so that the waterproof thermal insulation and heat insulation functions are significantly improved.
3. Egg white concrete cement foaming agent
It is made by the following method: first, mix cement, water, etc., according to a certain mass ratio, mix evenly, and prepare cement concrete slurry. Then stir the egg white with a mixer at high speed to form a uniform and fine closed-cell foam. Add a certain volume of foam to the cement concrete slurry. After mixing evenly, pour it into a mold for maintenance. The cement foaming agent has easy-to-obtain raw materials and simple foaming technology and overcomes the disadvantages of poor stability of traditional surfactants, insufficient raw materials, and high cost of animal and vegetable protein cement foaming agents.
4. Magnesium oxychloride cement foaming agent
First grind appropriate bone glue into powder, add glutinous rice flour, and add ten times water; heat it for about half an hour after the temperature reaches 75 degrees to form glue, and then mix it with detergent Wait for mixing, heat for about 5-10 minutes after the temperature reaches 75 degrees, and finally add water to dilute to make a product.
5. Cement foaming agent for engineering
Common ones are detergent, soapy water or fatty alcohol polyoxyethylene ether sodium sulfate, additives, edible salt, etc. Its manufacturing technology is as follows: the components are mixed and stirred evenly at normal temperature. The invention can produce a kind of foaming power that is very high, has excellent stability, and white bubbles, and can be widely used in the production of foamed concrete, foamed lightweight bricks, and foamed lightweight soil; also suitable for earth pressure balance shield Soil improvement in construction.
