The purpose of the ceramsite

Ceramsite has excellent performance, such as low density, high cylinder pressure strength, high porosity, high softening coefficient, good frost resistance, resistance to JianJiLiao excellent reactivity, and so on. Especially frac sand of the ceramsite density is small, internal porous, morphology, composition is uniform, and with a certain intensity and strong, thus has light weight, corrosion-resistant, antifreeze, and other multi-functional characteristics of seismic and well insulated. Using ceramsite these excellent performance, it can be widely used and building materials, gardening, food and beverage, fire-resistant insulation materials, chemical industry, petroleum and other departments, application field is more and more widely, and is still rising. At the beginning of the ceramsite invention and production, it is mainly used in building materials field, due to the continuous development of technology and people to know more deeply, the fracturing proppant of the ceramsite ceramsite already more than building materials this traditional scope of application of expanding its application in new areas. Applications of ceramsite in building materials, now has fallen to 80%, from 100% in other aspects of the application, has accounted for 20%. With the continuous development of new application of ceramsite, it will gradually increase the proportion of in other ways. Particles is all over the world to get fast development, because it has other materials do not have many excellent properties, the excellent performance, the excellent performance make it has the effect cannot be replaced by other materials. These excellent performance has the following several aspects. Density is small, light ceramsite its bulk density is less than 1100 kg/m3, generally is 300 ~ 300 kg/m3. Made with ceramsite as aggregate concrete density is 1100 ~ 1800 kg/m3, the corresponding concrete compressive strength is 30.5 ~ 40.0 Mpa. The biggest characteristic of ceramsite is appearance is hard, and there are many pores inside. These microporous give the haydite lightweight properties. 200 lytag concrete density is about 1600 kg/m3, and the same label of the density of ordinary concrete is up to 2600 kg/m3, both differ 1000 kg/m3. Heat preservation, heat insulation ceramsite due to internal porous, so has good insulation, the thermal conductivity of concrete prepared with it, as a general rule, be 0 ~ 0.8 W/(m, k), 1 ~ 2 times lower than the normal concrete. So, ceramsite architecture has good thermal environment.
