Properties Of Rapid Hardening Cement
Specific properties of the rapid hardening cement can work well in your favor. Some of the core factors of them are as follows:-
- It gains strength faster than the OPC.
- The final setting time is 30 mins to make your job done quickly.
- The soundness of the Cement is an autoclave.

- It is costlier and lighter than OPC.
Factors Affecting The Setting Of Rapid Hardening Cement
Despite being rapid, the time taken by rapid hardening cement depends on multiple factors. If you are planning on using rapid hardening cement anytime soon, you must keep these factors in mind. Some of the common factors that affect its setting may include:
Temperature
Higher temperatures will usually result in the faster setting of the cement, while a drop in the temperatures will slow down the setting process. This is not just the case when it comes to rapid drying cement; it is common to every cement regardless of its type.
Water And Cement Ratio
If the water and cement ratio is not properly balanced, that will affect the hydration levels and, in turn, will affect the setting time of the cement.
Fineness Of The Cement
When the cement particles are fine, they help in the better setting of the cement as they get an increased surface area for hydration.
Chemical Additives
If there are any chemical additives mixed with the cement, it will alter its setting time and might as well enhance some of the specific properties of the cement.
Manufacturing Of Rapid Hardening Cement
The rapid hardening cement is manufactured with the help of the dry process of cement manufacturing. At the beginning, argillaceous and calcareous materials are mixed with one another. The mixture is then allowed to burn at a clinkering temperature. Once it is burned, the clinker is grounded into a specific fineness. Once the burning is done, no other ingredient other than water, gypsum, or both must be added.
Disadvantages Of Rapid Hardening Cement
- Rapid hardening cement releases an excessive amount of heat, which results in the shrinkage cracks within the structure. Therefore, it must not be used in structures that come in contact with water or that are water resistant.
- Storing rapid heating cement can be very challenging. As it hardens really quickly and with very little amount of moisture, it requires a very dry place for storage.
- Rapid hardening cement is way more expensive than PPC or OPC. Therefore, it is not something that anyone can afford easily.
- No large concreting structures must be built with the help of rapid hardening cement. As it gives out a large amount of heat, it will cause the structure to crack in the process. Cracks in the structure of big buildings are extremely dangerous as there are chances that they may collapse easily by the slightest of earthquakes or any other external factors.
Final Take Away
