ქაფიანი ბეტონის უპირატესობები და უარყოფითი მხარეები

ქაფის ბეტონი is a lightweight concrete made by mixing fine aggregates, ქაფის აგენტები და წყალი. 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, მსუბუქი წონა, სითბოს შენარჩუნება, sound insulation and corrosion resistance. It can be produced with a variety of admixtures, including lime, თაბაშირი, cement and fly ash.

კომპრესიული ძალა: The compressive strength of ქაფის ბეტონი depends on the water-cement ratio, mix design and the type of foaming agent. It can be between 1.0 და 15 მპა, depending on the amount of foam and the grade of cement.

თბოიზოლაცია: The thermal properties of ქაფის ბეტონი 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: ქაფის ბეტონიs 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 ქაფის ბეტონი 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 ქაფის ბეტონი increases its mechanical performance. თუმცა, the CF must be preprocessed before being added to the concrete mixture.
