Apar-hormigoiaren abantailak eta desabantailak

apar-hormigoia is a lightweight concrete made by mixing fine aggregates, apar-agenteak eta ura. 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, pisu arina, beroaren kontserbazioa, sound insulation and corrosion resistance. It can be produced with a variety of admixtures, karea barne, igeltsua, cement and fly ash.

Konpresioaren indarra: The compressive strength of apar-hormigoia depends on the water-cement ratio, mix design and the type of foaming agent. It can be between 1.0 eta 15 MPa, depending on the amount of foam and the grade of cement.

Isolamendu termikoa: The thermal properties of apar-hormigoia 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: apar-hormigoias 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 apar-hormigoia 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 apar-hormigoia increases its mechanical performance. Hala ere, the CF must be preprocessed before being added to the concrete mixture.
