Polystyrene (STATE STANDARD R 51263-99) is a composite material consisting of Portland cement and its varieties, silica aggregate (silica sand or fly ash from thermal power station), a porous filler (foamed polystyrene granules)and modifying agents (setting accelerators, plasticizers, etc.)When we control the ratio of the components in the mixture we can get different brands of polystyrene on the indices of the average density in the dry state from D150 to D600. As a result we get both constructional and insulation material.
Due to good thermophysical properties of polystyrene this material can be used as an independent system of thermal insulation of external walls instead of using the so-called fastened insulation systems, where mineral wool, or a more popular solution – polystyrene is used as lagging.
Polystyrene concrete field of application for objects of housing and industrial construction is extremely wide:
- Production of ready-mixed polystyrene concrete mixtures of different density;
- Monolithic thermal insulation of attic floors and roofs;
- Erection of exterior walls in permanent shuttering for skeleton-type buildings;
- Insulation of external walls and surfaces of reconstructed buildings;
- Monolithic insulation of elements of exterior walls and floors;
- Monolithic exterior and interior walls and partitions;
- Manufacture of light insulation products for the construction of bearing and self-supporting elements (wall blocks, internal partition blocks, etc.).
