Answer / parveen kumar joshi lucknow

Water cement ratio are always same that is around 48% of the
weight of cement less cement less water high cement high
plastisizer by replacing water to increase the workability of
concrete.

what is water cement ratio m10,m15,m20,m25,m30,m35m ,m40..

More typical water-cement ratios of 0.4 to 0.6 are used.
The 1997 Uniform Building Code specifies a maximum 0.50
water-to-cement ratio (1:2).

what is water cement ratio m10,m15,m20,m25,m30,m35m ,m40..

Generally the water cencement ratio varies from 0.4 to 0.8 , It depends on grade of concrete as the grade of concrete increases w/c ratio bcome less.
W/c ratio is main cause of strengthening of concrete so if w/c ratio is less strength will be more and if w/c ratio is more strength will be less.

 Is This Answer Correct ? 19 Yes 3 No

what is water cement ratio m10,m15,m20,m25,m30,m35m ,m40..

M10 concrete is very low grade so
Water-192/cum
Cement-150/cum
Flyash-150/cum
So water cement ratio-0.64 is ok after 28days 25mpa
U need more strength add cement content 20kg
Using the admixture is best way-1.5/cum
Because workabality

Water-185
Cement-160kg/cum
Flyash-150kg/cum
W/c-0.59

Cemnt-200kg/cum
Flyash-170kg/cum
Water-176
W/c-0.47

Thank u
