**ADDING 4 LITRES OF WATER TO 1 CUBIC METER OF FRESHLY MIXED CONCRETE WILL:**

- Increase slump about 25 mm.
- Decrease compressive strength about 1.5 to 2 N/mm2.
- Increase shrinkage potential about 10%.

**IF TEMPERATURE OF FRESHLY MIXED CONCRETE IS INCREASED BY 1 DEGREE CELSIUS:**

- About 4 litres of water per cubic meter maintains equal slump.
- Air content decreases about 1%.
- Compressive strength decreases about 1.0 to 1.5 N/mm2.

**IF THE AIR CONTENT OF FRESHLY MIXED CONCRETE:**

- Increases 1% then compressive strength decreases about 0.5%.
- Decreases 1% then yield will decrease about 0.03 cubic meter per 1 cubic meter.
- Decreases 1% then slump decreases about 12.5mm.
- Decreases 1% then durability decreases about 10%.
