To make concrete foam, we first mix air sand or soft sand together with cement and finally with water in the mixer machine, then we dilute the foam in the foam maker chamber of the machine with water and use the air pump from The special pipe for small outlets is passed 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. After mixing the concrete completely using a pump, we pump it to the floors and spread and level 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 three days.
What are the Concrete Foam Executive Tips?
1. It is necessary before starting the work of floor construction with foam concrete, the work of facilities such as water and gas piping, electrical work, etc., which need to pass through the floor of the building; be finished.
2. That part of the building, which is supposed to be covered with concrete foam, must be completely cleaned of debris and materials, and the holes in the floor must be blocked with a layer of clay.
3. Before flooring with concrete foam, the floor must be completely leveled using a leveling hose or camera or laser leveling, etc.
What are the types of concrete foam?
High-density concrete foam (structural)
High-density concrete foam has a density of 1200 to 1800 kg/m3. This type of concrete foam is used for the construction of load-bearing walls, partition walls and prefabricated blocks for load-bearing members. Medium density concrete foam. >Medium density concrete foam has a density of 800 to 1000 kg/m3. This type of concrete foam is often used in the construction of prefabricated blocks for non-load-bearing members. With low density, it has a density of 300 to 600 kg/m3. This type of concrete foam is known as cellular lightweight concrete or abbreviated as CLC and lightweight concrete. Lightweight concrete is a very good option for sound and heat insulation. Foam concrete with low density has good resistance to fire, moisture and insect attacks. This issue has made it a good substitute for glass wool and wood wool.
