Weigh out the cement, sand, coarse aggregate and water separately as mentioned in the concrete mix design.Place the weighted quantities of coarse aggregate, fine aggregate and the cement in the pan or mixer.Fill the moulds (cube/cylinder) with obtained concrete in three layers of equal.height (approximately 50 mm).Each layer shall be uniformly tampered over the.the resulting concrete is of uniform color and proper workability.

Weigh out the cement, sand, coarse aggregate and water separately as mentioned in
the concrete mix design. Place the weighted quantities of coarse aggregate, fine aggregate and the cement in
the pan or mixer. Add the require quantity of water and mix the whole mass until. the resulting concrete is of uniform color and proper workability. Fill the moulds (cube/cylinder) with obtained concrete in three layers of equal. height (approximately 50 mm).Each layer shall be uniformly tampered over the. whole cross section of the mould with 35 strokes of tamping rod with the bullet. nose end having 16 mm diameter and 600 mm length. Care should be taken that the rod falls freely under its own weight from a height. about 150 mm. For (4” x 4”) cubes at least 25 strokes per layer is necessary 50. Remove the excess concrete with the trowel and level it.
