Vantaghji è disadvantages di Foam Concrete

béton spuma is a lightweight concrete made by mixing fine aggregates, foaming agents and water. It can be produced with natural or synthetic foaming agents.

Lightweight concrete has many advantages over conventional concrete, such as lower costs, faster construction, high energy efficiency and low environmental impact. It can be used in a wide range of applications including insulation, structural elements, filling of voids and grouting.

Its properties include a high strength-to-weight ratio, pesu ligeru, preservazione di u calore, sound insulation and corrosion resistance. It can be produced with a variety of admixtures, cumpresi calce, gesso, cement and fly ash.

Compressive strength: The compressive strength of béton spuma depends on the water-cement ratio, mix design and the type of foaming agent. It can be between 1.0 è 15 MPa, depending on the amount of foam and the grade of cement.

Isolamentu termale: The thermal properties of béton spuma are also affected by the pore structure and the size distribution of air voids. The narrower the air voids, the better the insulation.

Drying shrinkage: béton spumas have a lower drying shrinkage than ordinary concrete. This is because the air voids are more dense than the aggregate particles.

Currusioni: The cellular structure of béton spuma has a greater resistance to corrosion than the cellular structure of ordinary concrete. It is therefore an excellent choice for exterior protected constructions where corrosion is a problem.

Adding carbon fiber (CF) to the béton spuma increases its mechanical performance. Tuttavia, the CF must be preprocessed before being added to the concrete mixture.
