Abram's law gives the relationship between the strength of concrete and the water-cement ratio.
As per this law,
The strength of hardened concrete is inversely proportional to the water-cement ratio, only provided that the mix is workable.
Compressive strength of concrete = \(A\over B^\frac{w}{c}\)
where A and B are constants.
Additional InformationWater Cement ratio (W/C):
- It is the ratio of water's weight to cement's weight in a concrete mix. This ratio decides the strength and workability of concrete.
- The lower the water-cement ratio is, the higher the strength of concrete.
- A lower water-cement ratio is required when the concrete mix is mechanically compacted to achieve higher strength than the hand-compacted concrete mix with a higher water-cement ratio.
- A lower water-cement ratio leads to lower workability.
