ఫోమ్ కాంక్రీటు యొక్క ప్రయోజనాలు మరియు అప్రయోజనాలు

నురుగు కాంక్రీటు is a lightweight concrete made by mixing fine aggregates, foaming ఏజెంట్లు మరియు నీరు. 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, తక్కువ బరువు, వేడి సంరక్షణ, sound insulation and corrosion resistance. It can be produced with a variety of admixtures, including lime, జిప్సం, cement and fly ash.

సంపీడన బలం: The compressive strength of నురుగు కాంక్రీటు depends on the water-cement ratio, mix design and the type of foaming agent. It can be between 1.0 మరియు 15 MPa, depending on the amount of foam and the grade of cement.

థర్మల్ ఇన్సులేషన్: The thermal properties of నురుగు కాంక్రీటు 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: నురుగు కాంక్రీటుs 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 నురుగు కాంక్రీటు 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 నురుగు కాంక్రీటు increases its mechanical performance. అయితే, the CF must be preprocessed before being added to the concrete mixture.
