When Water is mixed in cement it starts a chemical reaction. Then hydration process starts and makes a cement paste. This paste can be moulded in any shape until it hardens. Cement continues to react with water and slowly starts losing its plasticity and ultimately hardens. Time taken to harden the cement after mixing water […]

Consistency of cement It is a minimum quantity of water requirement to start chemical reaction with cement to form a paste. Hence consistency test help to calculate minimum requirement of water to make cement paste. Standard Consistency: – Requirement of water for making cement paste can be found out by the plunger of the Vicat apparatus

Fineness of the Cement is tested to calculate how fine cement is. It helps to determine how fine and coarse particles are available in Cement. Fineness of the cement is directly Proportional to the hydration rate of the cement. More fine cement means fast rate of hydration. Fine Cement offers higher surface area. Higher surface
