Breiseáin Choincréite Éadrom | Gníomhairí Cúr Ardfheidhmíochta le haghaidh Coincréite Ceallacha
Is bloic thógála éadroma iad bloic stroighne cúr a bhfuil an neart struchtúrach céanna acu le brící traidisiúnta agus coincréit. Is féidir na bloic seo a úsáid le haghaidh feidhmeanna éagsúla. They have been designed to make construction easier and faster.
Structural bloic stroighne cúr 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 ft. They are more durable and resistant to cracking than conventional concrete blocks. Mar sin féin, 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. Ina theannta sin, foam blocks can be coated with thermal barrier coatings. These provide frost-free, non-cracking protection.
Go hiondúil, 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.
