Ordinary Portland Cement (OPC) Ordinary Portland Cement is prepared by a fullyautomated, dry manufacturing process using state of the art technology under strict quality assurance at all stages of manufacturing with the help of the "ROBOTIC (POLAB)" system.
OPC typically means Ordinary Portland Cement. This is standard concrete used for many purposes. PPC mean Pozzolanic PortlandCement. Pozzolans are siliceous material than can be added to concrete mixtures, potentially lower the mix cost without harming the performance characteristics.
There are lots of environmental impacts of Cement on our ecology. One of the major problems is emission of CO2 from the Cement industry. It is found that world yearly billion tons production of cement covers 7% of carbon dioxide''s yearly production. As CO2 is harmful for human health and also for the wild life. It causes many respiratory problems like asthma, bronchitis, and nasal infections.
