Final Setting Time of Ordinary Cement
The initial setting time of cement is the period of time during which cement can be moulded into any desired shape without losing strength. The final setting time of cement is the point at which it completely loses its plasticity and turns hard.
- The final setting time of cement is determined by the Vicat needle test. The time that cement takes to turn into a paste by mixing with water and begins to lose its plasticity is known as the initial setting time of cement.
- On the other hand, the time in which cement completely loses its plasticity by mixing with water and begins to have a certain structural strength is called the final setting time.
- It takes time to put cement paste in place after mixing cement and water, and it is required that cement paste or concrete be put in place before the initial setting time has passed.
- Initial setting time plays a major role in strength. i.e., 30 mins. And you shouldn’t disturb it until it has finished setting for the final time, which is 600 minutes for ordinary Portland cement.
