Переваги і недоліки пінобетону

пінобетону is a lightweight concrete made by mixing fine aggregates, піноутворювачі та вода. 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, конструктивні елементи, filling of voids and grouting.

Its properties include a high strength-to-weight ratio, легка вага, теплозбереження, sound insulation and corrosion resistance. It can be produced with a variety of admixtures, including lime, гіпс, cement and fly ash.

Міцність на стиск: The compressive strength of пінобетону depends on the water-cement ratio, mix design and the type of foaming agent. It can be between 1.0 і 15 МПа, depending on the amount of foam and the grade of cement.

Теплоізоляція: The thermal properties of пінобетону 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: пінобетонуs 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 пінобетону 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 пінобетону increases its mechanical performance. Проте, the CF must be preprocessed before being added to the concrete mixture.
