Concrete Mix Design Step by Step full Calculation

Concrete mix design is the process of detrmining right proportions of cement, sand and aggregates for concrete to achieve target strength of concrete. The Advantages of concrete mix design is that it gives the right proportions of materials, thus making the concrete use economical in achieving required strength of structural members.

Mix Design Fundamentals: Considerations for concrete for

Jul 31, 2014 · ‘Strength’ is the reciprocal of the w/c ratio—the lower the ratio, the higher the concrete strength. While it may be prudent for legal reasons to specify a minimum strength, it is just as well as to develop the mix design for slab-on-ground applications by specifying the maximum sack content, water-cement ratio, and aggregate quantity/size.

Constituent Materials of Concrete

Dry stone will absorb more water from the mix, and this can make concrete stiffer and more difficult to work, which may appear as visible problems in the finished concrete. Water in saturated stone has to be considered when calculating the amount of water to be added to the mix or the water ratio may be too high, resulting in weakened concrete.

Water-to-Cement Ratio and Aggregate Moisture Corrections

Consistency is the ability of freshly made concrete to flow. When used with different batches of the same mix design, a change in slump indicates a change in consistency and in the characteristics of the materials, mixture proportions, water content, mixing, time of test or the testing itself.
