6. Basic Considerations Cost • The cost of concrete is made up of • Material Cost • Equipment Cost • Labour Cost • The variation in the cost of materials arises from the fact that cement is several times costlier than aggregates. So it is natural in mix design to aim at as lean a mix as possible. Therefore, all possible steps should be taken to reduce the cement content of …

A wide variety of mix-design methods are used, varying from simple volumetric batching (by hand) of a 1:2:3 mix (cement:sand:coarse aggregate), to sophisticated, computer-based techniques, all of which are intended to produce a good-first-guess called a "trial mix." Then the trial mix has to be evaluated at lab- and field-scale, with the ...

The mix design for high strength concrete is determined by various factors such as the properties of cement, sand, aggregates, and water-cement ratio. The primary goal is to achieve a compressive strength above 40 MPa. To attain such strength, it is necessary to use the lowest possible water-cement ratio. However, this approach has a downside ...
