Concrete mix design is the process of finding the proportions of concrete mix in terms of ratios of cement, sand and coarse aggregates. For e.g., a concrete mix of proportions 1:2:4 means that cement, fine and coarse aggregate are in the ratio 1:2:4 or the mix contains one part of cement, two parts of fine aggregate and four parts of coarse aggregate.

Preparing the right mix. Depending on the application concrete mix design can be complex. The below table gives a basic indication of the mix ratios used for different purposes but should be used as a guide only. Some additional things to consider when finding a suitable mix design include but are in no way limited to the following:

Results indicate that the novel method can be applied to design concrete with C120 degree.

The choice of fine aggregate, whether it is manufactured or natural sand, can greatly impact the fresh concrete properties of a mixture such as the workability, pumpability, and finishability. Natural sand has an ideal shape for use as fine aggregate in concrete. The natural sand particles are well-rounded and are usually nearly spherical.

• Figure 6 shows how the fines content of the mix should be reduced as the sand becomes finer, ie as the percentage passing the 600 µm test sieve • A value is obtained from Table 2 for the strength of a mix made with a free-water/cement ratio of 0.5 according to the Chapter 5 Concrete Mix Design Calculations 25 .

May 22, 2018· Cement mix design is often mistakenly referred to "concrete mix design." However, cement is simply one of the ingredients of concrete. It is a binding substance that allows concrete to set, harden, and adhere to other materials. Therefore, it cannot and should not be used interchangeably with concrete mix design.
