ADDING 4 LITERS 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:

Add 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%.
