For Adding 4 Liters of Water in 1 m3 of Freshly Mixed Concrete
The slump value will be increased by 25 mm.
The compressive strength of concrete will be decreased by 1.5 to 2.0 N/mm2
The shrinkage potential will be increased by 10%.
1/4 bag of cement will be wasted.
If the Temperature of Freshly Mixed Concrete Is Increased by 1%, Then
4 liters of water per cu.m will give an equal slump.
The air content will be decreased by 1%.
The compressive strength of concrete will be decreased by 1.0 to 1.5 N/mm2.
If the Air Content of Freshly Mixed Concrete Is
If increased by 1% then the compressive strength will be decreased by 5%.
If decreased by 1%, the yield will be decreased by 0.03 cu.m per 1 m3.
If decreased by 1%, then the slump value will be decreased by about 12.5 mm.
If decreased by 1%, then the durability of the concrete will be reduced by 10%.
This was for the Thumb Rule Requirement.
