1.2 Importance of concrete mix design I. Quality concrete means • Better strength • Better imperviousness and durability • Dense and homogeneous concrete II. Economy a) Economy in cement consumption It is possible to save up to 15% of cement for M20 grade of concrete with the help of concrete mix design.
The mix ratio varies dependent on the intended use of the screed. In addition to cement type, grade of aggregate and the method of storage of screed material that also influence mix ratio to a certain extend. It is reported that, for traditional screeds a mix proportion of 1:6 Portland cement: sand/aggregate is a normal range that is commonly used.

But screeds should be able to provide sufficient support and strength to withstand the traffic under its intended use. Consistency of mix. Looking at consistency – concrete is mixed to a wetter consistency while the screed mix should be of a semi-dry, non-crumbly consistency. For concrete, the slump rates depend on the application and mix design.
