Uru na ọghọm dị na Foam Concrete

ụfụfụ ihe 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, ihe owuwu, filling of voids and grouting.

Its properties include a high strength-to-weight ratio, obere arọ, nchekwa okpomọkụ, sound insulation and corrosion resistance. It can be produced with a variety of admixtures, gụnyere wayo, gypsum, cement and fly ash.

Ike mkpakọ: The compressive strength of ụfụfụ ihe depends on the water-cement ratio, mix design and the type of foaming agent. It can be between 1.0 na 15 MPa, depending on the amount of foam and the grade of cement.

Ihe mkpuchi ọkụ: The thermal properties of ụfụfụ ihe 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: ụfụfụ ihes have a lower drying shrinkage than ordinary concrete. This is because the air voids are more dense than the aggregate particles.

Corrosion: The cellular structure of ụfụfụ ihe 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 ụfụfụ ihe increases its mechanical performance. Agbanyeghị, the CF must be preprocessed before being added to the concrete mixture.
