Impervious shale ceramsite

Shale ceramsite is at present a kind of energy saving material, with the characters of light volume, high compressive strength.

Refractory castable ceramsite

With performances of low density, light, heat preservation, heat insulation, good fire resistance, low bibulous rate, good resistance to heat shock and frost resistance and excellent resistance to alkali, refractory castable ceramsite are widely used among building materials, chemical industry, oil and other industries and the range of its applications is getting wider and wider.
