10+ CONCRETE MIX RULES OF THUMB YOU SHOULD KNOW
|Rules of Thumb on Concrete Mix
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 2.0 N/mm2
- Increase shrinkage potential about 10%
- Waste as much as ¼ bag of cement
If Freshly Mixed Concrete Temperature Increases 1 degree Celsius:
- About 4 liters 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 5%
- Decreases 1%, then yield will decrease about 0.03 cubic meter per 1 cubic meter
- Decreases 1%, then slump decreases about 12.5 mm
- Decreases 1%, then durability decreases about 10%
