If 4 litres of water is added with 1 cubic meter of newly blended concrete, the following result is obtained :-
1. Expand slump roughly 25 mm.
2. Lessen compacted strength around 1.5 to 2 N/mm2.
3. Enhance shrinkage potential nearby 10%.
If temperature of newly mixed concrete is enhanced by 1 degree celcius, the result will be as follow :-
1. Around 4 litres of water per cubic meter sustains identical slump.
2. Air content drops around 1%.
3. Compacted strength reduces approximately 1.0 to 1.5 N/mm2.
In case the air content of newly mixed concrete :-
1. Enhances 1% then compacted strength reduces roughly 0.5%.
2. Lessens 1% then produced result will reduce nearby 0.03 cubic meter per 1 cubic meter.
3. Lessen 1% then slump reduces nearly 12.5mm.
4. Drops 1% then strength reduces almost 10%.
