Ordinary Portland Cement (OPC) and Portland Pozzolana Cement (PPC) both are commonly used cement types for usage. Both of these types of cement vary in terms of strength, grade, setting time, cost, curing time, heat generation, etc. Banshiwala cement is one of the top manufacturers of PPC and OPC cement India, which is produced by the finest quality of minerals and a long grinding process. Our products are made keeping in mind the requirements of each and every sector therefore there is no compromise on the quality.
TOP MANUFACTURERS OF PPC AND OPC CEMENT INDIA- KNOW YOUR CEMENT
| PPC | OPC | |
| MANUFACTURING | Formed by grinding OPC clinker with Pozzolana materials ( volcanic ash, clay, slag, and silica fume ) and gypsum. Basically, it is a variant of OPC | This is the most common type of cement used made by grinding limestone and clay with gypsum to form minute cement particles. |
| STRENGTH | After curing PPC becomes more strong | Initial strength is higher than PPC |
| COST | Cheaper than OPC | Costlier than PPC |
| GRADING | No grades available, however, its strength matches OPC 33 grade after initial curing which happens after 28 days | Available in three grades on the basis of durability and strength i.e, OPC 33 OPC 43 OPC 53 |
| USAGE | They are widely used for marine construction, masonry, and plastering additionally they can be used in the same areas as OPC. | Commonly used in construction, like industrial and commercial spaces, road, defense structure, and flyovers. |
| HEAT OF HYDRATION ( Heat generated when water and cement reacts ) | The process is long and it produces comparatively less amount of heat which makes it ideal for mass concreting. | Produces more heat in less time and therefore can’t be used for mass concreting as it may result in cracks. |
| SETTING TIME | Initial setting time is 30 minutes but the final setting time is 25 days which helps in getting a better finishing. | Initial setting time is the same as PPC but the final setting time is 11 days. |
| RESISTANCE TO CHEMICALS | HIgher resistance against sulfate and chlorides. | Low resistance |
| ENVIRONMENTAL IMPACT | Is eco friendly as it constitutes of industrial waste | Emit C02 at the time of manufacturing |
| WORKABILITY ( how easily it can flow on the surface) | High | Low |
| DURABILITY | High | Low |
| CURING TIME | Minimum curing time of 10 days is required | Curing time is 7 days |
