Ceramsite has been rapid development in the world, because it has many excellent properties of other materials do not possess, this outstanding performance, this outstanding performance makes it with other materials can not replace the role of. The excellent performance of the following aspects.
Density of small, lightweight
The accumulation of Ceramics Prop own density is less than 1100kg/m3, generally 300 ~ 900kg/m3. With ceramsite concrete aggregate production is 1100 ~ 1800kg/m3, the compressive strength of concrete corresponding to 30.5 ~ 40.0Mpa. The biggest characteristic of ceramic proppant is hard appearance, while the interior has many micropores. These microporous give ceramsite lightweight characteristics. No. 200 of fly ash ceramsite concrete density is about 1600kg/m3, and the normal concrete with the same grade density is up to 2600kg/m3, the difference between the two 1000kg/m3.
The heat preservation, heat insulation
As the ceramic inner porous, so it has good thermal insulation, the thermal conductivity of concrete prepared with its rate is generally 0.3 ~ 0.8W/ (Mok), is lower than normal concrete is 1 ~ 2 times. Therefore, ceramic building has a good thermal environment.
Excellent flame resistance
Ordinary fly ash ceramsite concrete or fly ash ceramsite brick insulation, seismic, frost and fire resistance performance in one, especially the fire resistance is more than 4 times that of ordinary concrete. Refractory period of the same, the plate thickness of ceramsite concrete than ordinary concrete thin 20%. In addition, fly ash high density ceramic can be also formulated refractory refractory concrete degree of 1200 deg. In the high temperature of 650 DEG C, ceramsite concrete can maintain the normal temperature strength of 85%. While the ordinary concrete can maintain the normal temperature strength of 35% ~ 75%.
Good performance of the seismic resistant
Ceramsite concrete because of light weight, low elastic modulus, good deformation resistance, so it has better seismic performance. In the 1976 Tangshan earthquake, 4 buildings of ceramic ball concrete slab building built in Tianjin are largely intact, and can be used as usual. And its surrounding a considerable number of masonry buildings are subject to varying degrees of damage. Although this is related to the building structure and systems, but of ceramsite concrete has excellent seismic performance is also an important reason. The 1976 Italy fee Liuli area 9 earthquake occurred, the statistical data shows, brick and concrete building damage rate of 40% ~ 60%, the frame structure of clay hollow brick for building damage rate was 33%, while the ceramsite concrete building damage rate of only 5%. This shows that the seismic performance of ceramsite.
