폼 콘크리트의 장점과 단점

거품 콘크리트 is a lightweight concrete made by mixing fine aggregates, 발포제와 물. 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, 가벼운 무게, 보온, sound insulation and corrosion resistance. It can be produced with a variety of admixtures, 석회를 포함하여, 석고, cement and fly ash.

압축강도: The compressive strength of 거품 콘크리트 depends on the water-cement ratio, mix design and the type of foaming agent. It can be between 1.0 그리고 15 MPa, depending on the amount of foam and the grade of cement.

단열재: The thermal properties of 거품 콘크리트 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: 거품 콘크리트s 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 거품 콘크리트 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 거품 콘크리트 increases its mechanical performance. 하지만, the CF must be preprocessed before being added to the concrete mixture.
