⚡️Foam concrete is a mortar that consists of water, cement, foam (a chemical substance or based on animal protein from animal horns or venom) 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 concrete foam is light concrete.
ا Benefits of Concrete Foam
2. Insulating the facilities on the floor of the building
3. Excellent resistance to freezing as well as water penetration
4. The possibility of pumping it up to a height of 50 meters from the ground
5. Extremely high resistance to fire, lack of heat transfer
6. It is a little cheaper than the traditional method (concrete with mineral pumice).
7. The possibility of making a cut on the surface of foam concrete to implement or repair facilities
8. Very good thermal and sound insulation due to the presence of air and porous space
9. They have a light weight of about 400 to 1700 kg per cubic meter, which reduces the weight of the entire structure. 10. The execution speed is about 7 times faster than the traditional method, that is, if we execute 80 square meters of flooring with the traditional method, we can execute about 560 square meters in the same time with foam concrete.
🔰 How to execute and use concrete foam
💠 To make concrete foam, first we mix air sand or soft sand with cement and finally with water in the mixer, then we dilute the foam with water in the foam chamber of the machine and use the pump The air is passed through the tube for small outlets with high pressure to produce foam. In the next step, the foam is mixed with cement slurry and water in the mixer and small bubbles are formed in the whole. The mortar is spread. 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.
🌀 Concrete made of foam and cement is usually used as insulation in the floor and ceiling. While concrete foam made of sand, gravel, cement and foam are suitable for use in methods that require structural material due to their higher density. This light concrete is also used in the construction of roads, filling sewer holes and tunnels, and roof slopes.
