Define the meaning of Grout - Concrete
Grout should be made with any type of recommended cement and using water of a required quality. If very large size ducts are to be grouted, fine sand passing 150 micron sieve size can be used in the grout. Admixtures may also be used in the preparation of grout. The code specifies that water cement ratio for the neat cement grouts should be approximately 0.50 by mass. It should never exceed 0.55 by mass of cement. The compressive strength of the 100 mm cubes of the grout material should not be less than 17 N/mm2 at the age of 7 days. It is specified that the cubes should be cured in a moist atmosphere for the first 24 hours and subsequently in water.
