Mix design can be defined as the process of selecting suitable ingredients of concrete and determining their relative proportions with the object of producing concrete of certain minimum strength and durability as economically as possible One of the ultimate aims of studying the various properties of the materials of concrete plastic concrete and hardened concrete...

MINIMUM AND MAXMUM CEMENT CONTENT Ref SP 23 Handbook on Concrete Mixes Generally the cement content itself would not have a direct role on the workability of concrete mix for a given water-cement ratio then the compressive strength may increase with the richness of the mix However for a particular water-cement ratio...

Concrete mixing ratios for cement sand aggregate and water are generally mixed as 1 part cement 3 parts sand and 3 parts aggregate or stone with just enough water to make it workable This mixing ratio will give you a concrete mix that is strong durable and good for most concrete projects 4 33- 35 gallons of water or 133L...

The water to cement ratio is calculated by dividing the water in one cubic yard of the mix in pounds by the cement in the mix in pounds So if one cubic yard of the mix has 235 pounds of water and 470 pounds of cement- the mix is a 50 water to cement ratio...
