Aditivos ligeros para hormigón | Agentes espumantes de alto rendimiento para hormigón celular
Los bloques de cemento celular son bloques de construcción livianos que tienen la misma resistencia estructural que los ladrillos y el concreto convencionales.. Estos bloques se pueden utilizar para una variedad de aplicaciones.. They have been designed to make construction easier and faster.
Structural foam cement blocks have a basic core that is coated with a thick layer of cementitious material. This provides the necessary strength to support loads up to those required for highways. The blocks are also designed to resist rot and fire.
Each block has a flat surface at its bottom edge. It also has an upwardly inclined surface at its upper edge. At the end of this surface is a groove that is connected to the next block.
The outer surface of the blocks is coated with a thin fiberglass reinforced cement. This increases the load-bearing capability of the foam core.
Foam concrete buildings can be constructed with typical spans of 6 m and 20 pie. They are more durable and resistant to cracking than conventional concrete blocks. Sin embargo, the thickness of the core and the type of coatings can vary according to the type of structure.
Foam concrete buildings can withstand hurricane force winds. They can also be constructed to stand up to earthquakes. Además, foam blocks can be coated with thermal barrier coatings. These provide frost-free, non-cracking protection.
Típicamente, foam concrete blocks are made with a density of 2 pcf or less. These systems are suited for buildings with low to moderate loads and are compatible with several different kinds of accelerators and retarders.
