What is Setting Time of Cement?
Initial Setting Time of Cement. Initial setting time of cement is the time when the paste (cement + water) starts losing its plasticity. This mean that if the initial setting time of cement is 30 minutes, the cement mortar or concrete must be placed in position within 30 minutes of adding water. If delayed, mortar or concrete will lose strength.
