  4. The Miscellaneous Thumb Rules in Construction  

One m2 = 10.763 ft2

One m3 = 35.314 ft3

One Acres = 4046.873

m2 = 43560.17

ft2 = 4840.019 Yards

One Cubic meter = 1000 liter

One Meter = 3.280 Feet

One Mile = 1609.344 meter

One Acre = 100 cent

One ground = 2400

Sft = 5.51 cent

½ ground = 2.75 cent

One Mile = 8 Furlong

One cement bag = 1.25 ft3

One Forma box = 1*1*1.25 feet

 


 

 

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.
