10 Concrete Mix Thumb Rules Useful For Every Engineers

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%.
