What is a concrete foam?
Foam concrete is a mortar that consists of water, cement, foaming agent (a chemical substance or based on animal protein from animal horns or hooves) and air sand or soft sand. The density of foam concrete is very low, and it is also a good sound and thermal insulation, which is quick and easy to implement, and in terms of the finished price, it is a little cheaper than the traditional method (pumice concrete). Another name for foam concrete is light concrete.
Foam concrete is a new coating that has recently entered the construction industry.
This type of concrete has a weight of about 400 to 1700 kg per cubic meter, depending on the weight and mixing plan of its ingredients after complete drying.
Many people think that foam Concrete is one of the new materials in the construction industry, but it is interesting to know that since 1980, with the cooperation of German and European universities, foam concrete has been used and introduced all over the world. clc block factory entered the Iranian construction industry market and after a few years they used concrete foam in the flooring and roof slope of the projects.
How to run the concrete foam
To make concrete foam, we first mix air sand or soft sand with cement and finally with water in the mixer machine, then we dilute the foam in the foam chamber of the machine with water and use an air pump. It is passed through a special pipe for small outlets with high pressure to produce foam. In the next step, the foam created in the mixer is mixed with cement slurry and water, and small bubbles are spread throughout the mortar. be. After mixing the concrete completely using a pump, we pump it to the floors and spread it on the surface with a thickness of about 10 cm. After the completion of its full implementation, to prevent surface cracks, the concrete surface must be wet for at least 3 days.
