The use of exfoliated vermiculite in construction

Buildings & Constructions

Modern civil and industrial construction makes ever greater demands for building materials for a variety of parameters such as: ease of use, efficiency, durability, environmental, fire safety, etc.

To a large extent all the above qualities has a modern building material – expanded vermiculite. Due to its porous structure, expanded vermiculite is an excellent heat and sound insulator, which makes it an indispensable application as bulk insulation for floors and roofing. In this case, there is a substantial savings because of their energy saving properties of expanded vermiculite significantly (7-10 times!) Is superior to traditional building materials such as concrete or brick.

Increasing use is being expanded vermiculite, and as part of the dry mortar and plaster. For example, the standard plastering the walls of the cement-vermiculite mortar 5 times greater than for similar teplosberezheniya plaster of cement-sand mortar.

And the exceptional ease of expanded vermiculite, along with the already mentioned high heat and sound insulating properties allow wide use of vermiculite as a filler in the manufacture of lightweight concrete and gypsum concretes and cements teplogidroizolyatsionnyh based bituminous binders.

High thermal stability of exfoliated vermiculite, finds its application in the manufacture of fireproof tiles and wall materials.

In short, the scope of the vermiculite in construction is wide enough and it will find increasing application in the development of construction technologies.

In conclusion, we list the current use of exfoliated vermiculite in construction:

  • as fill insulation;
  • in a dry building mixtures and plasters;
  • as a filler lightweight concrete;
  • as a filler teplogidroizolyatsionnyh mastics;
  • the device self-leveling floors;
  • in the production of heat-resistant wall panels and partitions;
  • as heat and sound insulator.
