![]() ![]() Design of concrete mix needs not only the knowledge of material properties and properties of concrete in plastic condition it also needs wider knowledge and experience of concreting. The design of concrete mix is not a simple task on account of the widely varying properties of the constituent materials, the conditions that prevail at the site of work, in particular the exposure condition, and the conditions that are demanded for a particular work for which the mix is designed.ĭesign of concrete mix requires complete knowledge of the various properties of these constituent materials, these make the task of mix design more complex and difficult. ![]() One of the ultimate aims of studying the various properties of the materials of concrete, plastic concrete and hardened concrete is to enable a concrete technologist to design a concrete mix for a particular strength and durability. 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. ![]()
