Thumb Rules For Concrete Mix Design

For including 4 liters of water in 1 cu.m crisply blended cement

1. The slump esteem will be expanded by 25 mm.

2. The compressive quality of solid will be diminished by 1.5 to 2.0 N/mm2

3. The shrinkage potential will be expanded by 10%.

4. 1/4 pack of bond will be squandered.

On the off chance that the temperature of naturally blended cement is expanded by 1%,

1. 4 liters of water for each cu.m will give measure up to droop.

2. The air substance will be diminished by 1%.

3. The compressive quality of solid will be diminished by 1.0 to 1.5 N/mm2.

On the off chance that the air substance of newly blended cement is

1. Expanded by 1% then the compressive quality will be diminished by 5 %.

2. Diminished by 1%, yield will be diminished by 0.03 cu.m per 1 cu.m.

3. Diminished by 1%, at that point the droop esteem will be diminished about 12.5 mm.

4. Diminished by 1%, at that point the sturdiness of the solid will be decreased by 10%.
