3. Initial and Final Setting Time Of Cement Test. Initial Setting Time gives an idea about how fast cement can start losing its plasticity and the final setting time of cement gives an idea about how much Time cement takes to lose its full plasticity and gain some strength to resist pressure.. Initial Setting Time of Cement: It is the time elapsed between the moments that the water is added to

The Properties of Ordinary Portland Cement and Physical Tests on Cement. Cement is a commonly used binding material in the construction. The cement is obtained by burning a mixture of calcareous (calcium) and argillaceous (clay) material at a very high temperature and then grinding the clinker so produced to a fine powder.

C 3 S gives the cement its initial strength, and makes it harden rapidly. On the other hand, C 4 AF has little to do with strength, but imparts the gray color to ordinary Portland cement. ‘Heat of hydration’ is the term used to describe the heat released when cement reacts with water during the formation of concrete.
