The durability of a reinforced concrete monolithic wall depends on influence of external environment: rain and sun, heat and cold. Especially dangerously cyclic thermal expansion compression of a bearing wall in the presence of moisture. In a timbering from thermoblocks the concrete wall is isolated from influence of external environment by an expanded polystyrene 50 mm thick layer. Service life of the concrete wall protected from influence of external environment and temperature differences is almost unlimited.
Expanded polystyrene also completely keeps the properties eventually. Research of 27 years' penopolistirolovy isolation did not find aging signs. The accelerated laboratory researches feigning the 100th summer term of operation also did not find aging signs.
Long influence of ultra-violet radiation causes superficial fragility of expanded polystyrene which does not influence heat-insulating properties, but can cause a material erosion from impact of a rain and wind. Therefore the surface of expanded polystyrene is protected finishing materials.
2. Why "Termod" is under construction quicker?
Assembly of a timbering from thermoblocks reminds folding from cubes of the meccano of the toy house. Hollow thermoblocks have special castle parts by means of which easily and strongly connect with each other. The geometrical sizes of thermoblocks have machine-building accuracy. Therefore, having exposed properly the first row of thermoblocks, the others at installation "automatically" form "ideal" geometry of a wall. One square meter of a wall is formed by installation of only four thermoblocks with a gross weight of 3 kg. Filling by concrete of 15 centimetric walls will also not take away a lot of time.
Possibilities of technology "Termod" were shown by the GarantDesign company the Two-storeyed house with a total area of 112 sq.m was constructed in 5 days. With all communications, finishing works and furniture.
3. What concrete is filled in in a timbering from thermoblocks?
Ordinary heavy concrete of the class V-25 with fraction of crushed stone of 5-20 mm of a plastic consistence. No additional additives, and also a vibrotrombovaniye are required. Concrete mix can be prepared directly on a building site. So, concrete of the following structure quite will be suitable for a two-storeyed cottage: 1 parts of cement of the M400 brand, 3 parts of sand and 5 parts of crushed stone of fraction 5-20. It is not recommended to try to obtain concrete fluidity at the expense of a cherezmerny amount of water.
4. How to calculate the required number of thermoblocks and concrete?
1 sq.m of a wall requires 4 thermoblocks; 0,128 CBM of concrete and 4 kg of fittings.
The number of thermoblocks (piece) = the Area of walls of the house in sq.m x 4
Amount of concrete (CBM) = the Area of walls of the house in sq.m x 0,128
The number of fittings (kg) = the Area of walls of the house in sq.m x 4
