Portland pozzolana cement also abbreviated as PPC Cement. We recommend you to check whether the PPC cement brand that you purchase adhere to IS code.
Cement, generally, adhesive substances of all types, but, during a narrower sense, the binding materials utilized in building and engineering construction. The cement of this type is finely ground powders that, when mixed with water, set to a tough mass. Setting and hardening result from hydration, which may be a chemical combination of the cement compounds with water that yields submicroscopic crystals or a gel-like material with a high area. due to their hydrating properties, constructional cement, which can even set and harden underwater, are often called Portland cement. the foremost important of those is hydraulic cement.
