Ordinary Portland Cement (OPC)
Ordinary Portland cement refers to the hydraulic binding material ground by mixing Portland cement clinker, blended materials and appropriate amount of gypsum. The Bureau of Indian Standards (BIS) has specified to use OPC in pre-stress concrete structures which are typically used in high rise buildings, foundation systems, bridge and dam structures, silos and tanks, industrial pavements and nuclear containment structures. |

Portland Pozzolana Cement (PPC)
Portland Pozzolana Cement is made by mixing OPC with pozzolanic (siliceous) materials such as silica, volc`anic ash, fly ash, pond ash, etc. PPC is believed to be the product of the future, considering it various applications in the construction industry. They are suitable to use in hostile environmental conditions. They can be reliably utilised in the construction of marine structures, masonry mortars and plastering, hydraulic structures.

Portland Slag Cement (PSC)
Slag cement is a hydraulic cement formed when granulated blast furnace slag (GGBFS) is ground to suitable fineness and is used to replace a portion of Portland cement. It is a recovered industrial by-product of an iron blast furnace. Molten slag diverted from the iron blast furnace is rapidly chilled, producing glassy granules that yield desired reactive cementitious characteristics when ground into cement fineness.
