8o Initial setting time is the time when the paste starts losing its plasticity.
Occurs when the cement has hardened to the point at which it can sustain some load. Later revibration can be beneficial but as the reactions between the cement and water continue the mass loses 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. Initial setting time is the time when the paste begins losing its plasticity. Initial setting time test is crucial for transportation placing and compaction of cement concrete.
