The Portland Pozzolana Cement is a kind of Blended Cement which is produced by either inter grinding of OPC clinker along with gypsum and pozzolanic materials in certain proportions or grinding the OPC clinker, gypsum and Pozzolanic materials separately and thoroughly blending them in certain proportions.
The main component of OPC and the material that gives it strength, clinker, is produced by sintering a well-defined raw meal made of limestone mixed with one or more sources of Si, Al, and Fe at ...
OPC grade 53 is produced by grinding clinker, gypsum, and other additives such as limestone, fly ash, or slag. The proportions of these components are measured and finely grinded to form a powder. This powder is then mixed with water to form a paste that hardens over time, making it an excellent binding material for construction purposes. ...
The present study suggests, clinker samples collected from all zones are suitable for PLC preparation, however, more grinding energy is required to prepare PLC while using clinker from the North and West zone. Clinker of East and North zone has high alkali content which adversely affect the durability of concrete prepared by using PLC.
Steel-slag can be used to produce energy-saving cement by co-grinding with OPC clinker and blastfurnace slag. In such preparations OPC clinker is about 15-30%, steel-slag around 30-40% and blastfurnace slag is around 40-50%. 3. Producing energy-saving steel-slag cement can save energy, natural resources and cut GHG …
