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
water in high grade cement slump ratio is increased by adding
plastisizer by replacing water to increase the workability of
concrete.

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

Answer / yogesh

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.

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

Answer / p.s.vijaya bhaskar

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

M20 grade
Water-185
Cement-160kg/cum
Flyash-150kg/cum
W/c-0.59

M30-grade
Cemnt-200kg/cum
Flyash-170kg/cum
Water-176
W/c-0.47

Thank u
