Polystyrene - an extender for manufacture of light concrete
(polystyrene concrete)
The description of a material
An extender "Polystyrene" is granulated
foam polystyrene material (a ball in diameter 3-8 mm) with white color,
non-polluting material both having excellent thermal isolation and soundproofing
characteristics. Balls pass special processing that allows them
to mix with water and cement so, that they do not emerge on a surface,
and form homogeneous structure.
" Polystyrene " is the basic component at manufacturing of
polystyrene concrete mixes from cement and water.
the Basic advantages of concrete on the basis of light
foam polystyrene extender:
-
Excellent thermal isolation and acoustic protection properties;
-
uniformity of structure;
-
high durability ;
-
There is an opportunity of preparation directly on a building site ;
-
Transportation of fresh concrete mix by pump to a place of stacking.
Sphere of application:
Preparation of polystyrene concrete and its stacking
All components are loaded in concrete mixed installation in
the following sequence: water, polystyrene balls, cement .
It is necessary to mix within 10 minutes up to homogeneous structure. With the help of the pump
polystyrene concrete moves on flexible hoses to a place of stacking. When
temperature is lower than + 5°Ñ liquid anti-frosty additives are used.
The surface on which the material is stacked, is beforehand carefully cleared from
dust and also it is moistened with water. In a warm season polystyrene concrete hardens for two day.
