All these substances mix ratios depends totally in the construction types and designs of mix. However, the building codes give the standard as well as nominal concrete mixture ratios for different construction works depending on the testing and experience. All these concrete mix type ratios are clearly explained below. Types of Concrete Mix Ratio and their Strengths Nominal Concrete Mix Ratios Generally in past, the concrete specifications had recommended the proportions of cement, coarse and fine aggregates. These constant cement-aggregate ratio mix that gives the sufficient strength are marked as the nominal mixes. These nominal mixed provide simplicity and in normal circumstances, they do consists a strength more than specified. But due to difference in ingredients mix, these nominal concrete ratio for the workability given would widely vary in terms of strength. Nominal mix ratios for these concrete mix are 1:2:4 for M15, 1:1.5:3 for M20 etc. Standard Mixes or Ratio The nominal mixes as mentioned above for cement aggregate ratio would result in wide variation of strength and also could lead to over or under-rich mixes. That why, the minimum compressive strength has got added in most of the specifications and it is called as standard mixes. IS 456 2000 model has designated it’s concrete mixes as M40, M35, M30, M25, M20, M15, M10. which are called as number of grades. In it the letter M indicates the mix and also the the twenty eight day cube strength mix in the units of N/mm2. Designed Mix Ratio of Concrete In this designed mixes, the concrete performance of given by the designer but the proportions or mix is specified by the concrete producer. However, the content of minimum cement could be excluded and can be paid down. This method is used mostly for the mix proportions sections that includes particular materials in mind consisting of less or more unique characteristics. This technique gives the concrete production with appropriate properties most economically. However, these designed mixtures does can not be the guides as they doesn’t assure the exact mix proportions for the required performance. Table given below gives the details of various types of concrete mix ratios and their strengths.
