cenosphere is a Construction Materials Agents product. Key specs — Origin: China (Mainland).
Product Description
A cenosphere is a lightweight, inert, hollow sphere filled with inert air or gas, typically produced as a byproduct of coal combustion at thermal power plants. The color of cenospheres varies from gray to almost white and their density is about 0.41.0 g/cm³, which gives them a great buoyancy.Chemical compositions: SiO2 Al2O3 Fe2O3 CaO MgO Na2O+K2O TiO2
