EPS concrete block
Autoclaved aerated concrete block is a kind of light-weight wall material which is mostly commonly used at present. However, along with the social development and the enhancement of people’s living demands, it could not meet the basic requirements on modern architecture on energy saving (energy-saving indexes: thermal transmission coefficient, and thermal inertia index). EPS (polystyrene) concrete energy-saving block takes polystyrene foaming particle as the main raw material, and enjoys the optimal heat-preservation effect at present. Autoclaved aerated concrete block has relatively great water absorption, and is easy to induce empty plump and crack in case of surface coat. On the contrary, EPS (polystyrene) concrete energy-saving block has relatively small water absorption, and could reduce serial problems such as empty plump and crack, etc. on internal and external walls; meanwhile, this product many enhance the intensity grade (A2.5-A3.5) according to design requirements.
At present, no material for external heat preservation of envelop (external wall) structure has passed a test, and the working procedures are very complex. Common external heat preservation is conducted by fastening adhesives or other substances to wall body, which just could not be integrated with the wall body. After the tests of wind, sunshine, ice, snow and high temperature, most walls will have the common problems unavailable to prevent, such as the break-off and crack of external heat-preservation layer of external walls, etc. EPS (polystyrene) concrete energy-saving block takes polystyrene foaming particle as the main raw material, its heat-preservation wall is of “two in one”, and without additional heat preservation, it is possible to avoid the common problems such as the break-off and crack of external heat-preservation layer of external walls, etc. The external heat-preservation procedure of envelop (external wall) structure is complex and of great difficulty, so the construction period is long, and the construction must be implemented by professional personnel. EPS (polystyrene) concrete energy-saving block is made in the specification most convenient for construction, and is a product easy to understand and for simple and quick construction.
