  • Consistency means amount of water needed to prepare a plastic mix.
  • Consistency test is done using Vicat's appartus.
  • Consistency of cement should be less than 30%
  • consistency test is used to find the amount of water to be mixed with cement.It is necessary to find the consistency because amount of water present in the cement paste may affect the setting time.standard consistency is indicated by the vicat plunger reading (5 to 7) from the bottom of mould(IS 4031 (part 4)1988)

To determine initial and final setting time, the amount of water needed to make standard paste is required. So the significance of consistency test comes into play as it helps to determine the amount of water used to make standard paste.

Besides, cement consistency affects workabilty of concrete(slump) and the workabilty of cement is affected by cement paste.

Also strength of cement classes(32.5/42.5/52.5) and other properties of cement are measured at specified consistancy rather than at specified water-cement ratio.

the amount of water content that brings the cement past to a standard condition of wetness is called "normal consistency".

It refers to the ability of cement to flow. a paste is said to have a normal consistency when the plunger of the Vicat's apparatus penetrate it by 10_+1 mm.

What is standard consistency of a cement paste?

It is normal for Ordinary Portland cement to have a consistency ranging from 25-35%. To prepare cement paste of standard consistency, 25-35% of water must be added to cement. For a more detailed explanation, let us assume that a standard consistency is 30%. To make this quantity, add 30% water to 400g of cement.

What is the property used to classify media and refers to the medium's normal consistency?

Viscosity is the property used to classify media based on its normal consistency. Viscosity refers to the resistance of a fluid to flow, with high viscosity indicating a thicker consistency and low viscosity indicating a thinner consistency.
