Understanding Extra Rapid Hardening Cement
Extra rapid hardening cement is specifically designed to achieve higher strength in a shorter time frame, making it ideal for situations where quick setting is crucial.
Key Method for Production
The correct answer is option 'D': By inter-grinding Rapid Hardening cement with calcium chloride. Here’s why:
Calcium Chloride as an Accelerator
- Accelerator: Calcium chloride acts as an accelerator, speeding up the hydration process of cement.
- Increased Strength: When mixed with rapid hardening cement, it enhances the early strength gain, allowing structures to support loads sooner.
Other Options Explained
- Option A: Addition of up to 5% gypsum in Ordinary cement.
- Role of Gypsum: Gypsum is primarily used to control the setting time of cement but does not significantly enhance rapid hardening properties.
- Option B: Production through dry manufacturing.
- Dry Manufacturing Process: While this method is efficient, it does not specifically lead to extra rapid hardening characteristics.
- Option C: By mixing Ordinary Portland Cement with blast furnace slag.
- Effect of Slag: While slag can improve certain properties, it generally slows down the setting time and is not suitable for rapid hardening.
Conclusion
In summary, the inter-grinding of Rapid Hardening cement with calcium chloride is the most effective method for producing extra rapid hardening cement, ensuring that structures can be erected quickly and efficiently when time is of the essence.
