Use a maximum 45 water to cement ratio for concrete with severe or very severe sulfate conditions per the 1997 Uniform Building Code (Table 19-A-4) Water permeability increases exponentially when concrete has a water cement ratio greater than 50 Durability increases the less permeable the concrete mix is
For concrete mixing ration in M30 grade concrete the mix has to be designed after testing all the materials including water in labs When you go for higher grade of concretes the mix has to be designed it is the water to cement ratio which has to be monitered for higher grades of concrete
However a mix with a ratio of 0 35 may not mix thoroughly and may not flow well enough to be placed More water is therefore used than is technically necessary to react with cement Water–cement ratios of 0 45 to 0 60 are more typically used For higher-strength concrete lower ratios are used along with a plasticizer to increase flowability
