What is initial Setting time?
An arbitrary division has been made for the setting time of cement as initial setting time and final setting time.It is difficult to draw a rigid line between these two arbitrary divisions.For convenience,initial setting time is regarded as the time elapsed between the moment that the water is added to the cement,to the time that the paste starts losing its plasticity.The final setting time is the time elapsed between the moment that the water is added to the cement ,and the time when the paste has completely lost its plasticity and has attained sufficient firmness to resist certain definite pressure.
