Hafif Beton Katkıları | Hücresel Beton için Yüksek Performanslı Köpük Maddeleri
köpük beton 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, yapısal elemanlar, filling of voids and grouting.
Its properties include a high strength-to-weight ratio, hafif, ısı koruma, sound insulation and corrosion resistance. It can be produced with a variety of admixtures, kireç dahil, alçıtaşı, cement and fly ash.
Basınç dayanımı: The compressive strength of köpük beton depends on the water-cement ratio, mix design and the type of foaming agent. It can be between 1.0 Ve 15 MPa, depending on the amount of foam and the grade of cement.
Isı yalıtımı: The thermal properties of köpük beton 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: köpük betons 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 köpük beton 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 köpük beton increases its mechanical performance. Fakat, the CF must be preprocessed before being added to the concrete mixture.
