Polytherm

The decisive factor for the strength of the polytherm is the structure of hardened cement paste, surrounding particles of foamed plastic fillers, which affects the mass of concrete. In addition, the shape and size of the grains, as well as the surface structure of the polystyrene foam aggregates used, are important. Unlike mineral fillers, the dosage of expanded polystyrene fillers is not determined by mass, but by volume. Thus, it is possible to precisely set the volume of pores and, thanks to this, the volume mass of polystyrene concrete, and to produce polystyrene concrete with a structure with closed pores.

Properties and characteristics of polytherm

• low volume mass,
• good thermal insulation of foamed particles, thanks to which there is practically no water absorption,
• spherical shape, which is better from the point of view of static loads.
• excellent sanitary and epidemiological indicators,
• excellent comfort of living in houses made of polystyrene concrete,
• good vapor permeability and environmental cleanliness of polystyrene concrete structures are dry (no more than 4% humidity),
• in case of wetting of constructions in an emergency situation, the polytherm and its products dry quickly without loss of strength;
• the highest ratio of density to heat-insulating capacity among analogues;
• the highest ratio of moisture resistance to thermal insulation capacity among analogues;
• the highest ratio of durability to heat-insulating capacity among analogues;
