Coking Cement Vs Thermal Cement

Concrete by itself has a very low rvalue a measure of thermal resistance its insulation value comes primarily from using it in thick slabs and hence isolating the insulated space from thermal.

We are a mining equipment company integrating scientific research, production and sales, committed to the production of mining equipment and the development of environmental protection.
