What is setting time of cement?

Question

Accepted Answer

Setting time of cement refers to the time taken for the cement to harden and gain strength.

Setting time is an important property of cement as it determines the workability and handling time of concrete.
It is influenced by factors such as cement composition, fineness, water-cement ratio, temperature, and admixtures.
The initial setting time is the time taken for the cement to stiffen and resist penetration by a standard needle, usually around 30 minutes.
The final setting time is the time taken for the cement to completely harden and develop its full strength, typically around 24 hours.
Different types of cement have different setting times, such as rapid-setting cement which hardens quickly.
Controlling the setting time is crucial in construction to ensure proper placement, curing, and strength development of concrete.

Accepted Answer

Initial setting time 30 min and final setting time 600min
