Күпчелек бетонның өстенлекләре һәм кимчелекләре

күбек бетон is a lightweight concrete made by mixing fine aggregates, күбекләү агентлары һәм су. 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, җиңел авырлык, җылылыкны саклау, sound insulation and corrosion resistance. It can be produced with a variety of admixtures, including lime, гипс, cement and fly ash.

Кысу көче: The compressive strength of күбек бетон depends on the water-cement ratio, mix design and the type of foaming agent. It can be between 1.0 һәм 15 MPa, depending on the amount of foam and the grade of cement.

Rылылык изоляциясе: The thermal properties of күбек бетон 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: күбек бетонs 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 күбек бетон 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 күбек бетон increases its mechanical performance. Ләкин, the CF must be preprocessed before being added to the concrete mixture.
