Read about the basics of concrete mix design, including how to adapt the mix to achieve the desired placeability, strength, durability, density, and appearance.
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.
Concrete Mix Design. Introduction. The process of selecting suitable ingredients of concrete and determining their relative amounts with the objective of producing a concrete of the required, strength, durability, and workability as economically as possible, is termed the concrete mix design.

Concrete Mix design is to arrive at proportions. A Step-by-Step detailed concrete Mix design Procedure to calculate cement, sand, aggregate, water & admixture content in to prepare M30 Grade concrete.
Many specifying authorities seek to assure the quality of concrete provided to them by choosing a prescriptive approach that narrowly defines the quality or source of raw materials, and the proportions in which they are used. This is preferred by some concrete suppliers because it relieves them of ...
A concrete mix is a combination of cement, water, coarse and fine aggregates, and air. Different proportions of these materials give the concrete different levels of strength, durability, and workability.
Aggregate shape's effect on concrete quality. By Frank Bowen. Editor's Note: This is the second article in a year-long series that explores the science of concrete to provide a better understanding of mix design.
