Types of Concrete Mix Ratio Design and their Strengths
Concrete ratios are part of the concrete components including sand, cement, water, and aggregates. To help you get a better idea of concrete mix ratio and designs you can choose Concrete Mix NZ that will give you complete knowledge you will find very informative.
The most fascinating thing that different building codes provide standard and nominal concrete mix ratios for several constructions based on work experience and testing. |
Here are types of Concrete Mix ratios that you should know,
1) Nominal concrete mix ratio:
In past years the specification for concrete was prescribed by the proportions of cement course. These mixes of fixed aggregate cement ratio ensure to have enough strength to use.But today nominal mixes offer the simplest way with the margin of strength and variability of different mixed ingredients for nominal concrete.
A nominal mix ratio for concrete are (1:2:4) for M15, (1:1.5:3) for M20.
Normal grades of concrete
Concrete grade: mix ratio: Mpa(N/mm) PSI
M5 1:5:10 5Mpa 725 PSI
M7.5 1:4:8 7.5Mpa 1087 PSI
M10 1:3:6 10Mpa 1450 PSI
M15 1:2:4 15Mpa 2175 PSI
M20 1:1.5:3 20Mpa 2900 PSI

M15 1:2:4 15Mpa 2175 PSI
M20 1:1.5:3 20Mpa 2900 PSI
2) Standard ratio or mixes:
The standard mixes of fixed cement aggregate ratio vary in strength and may result with a minimum compressive strength that also has been included,
The mixes for standard ratio mixes respectively are M10 (1:3:6) M15 (1:2:4), M20, (1:2.5:3) and M25 (1:1:2).
Standard grade of concrete
Concrete grade: mix ratio: Mpa(N/mm) PSI
M25 1:2:1 25Mpa 3625 PSI
M30 Design mix 30Mpa 4350 PSI
M35 Design mix 35Mpa 5075 PSI
M40 Design mix 40Mpa 5800 PSI
M45 Design mix 45Mpa 6525 PSI
3) Designed a mixed ratio of concrete:
In the mixes and performance of the concrete, it is specified that the Concrete Mix NZ has already determined the production of concrete, except the minimum cement requirements.
The most rational approach to select the designed mix ratio with specific materials is to understand the production of concrete with appropriate properties economically.
However, the designed mix ratio does not serve as a first choice and can’t guarantee the correct mix proportion about the performance.

High strength concrete grade
Concrete grade: mix ratio: Mpa(N/mm) PSI
M50 Design mix 50Mpa 7250 PSI
M55 Design mix 55Mpa 7975 PSI
M60 Design mix 60Mpa 8700 PSI
M65 Design mix 65Mpa 9425 PSI
M70 Design mix 70Mpa 10150 PSI
Final verdict:
The concrete mix NZ that are used with nominal and standard mixes are prescribed to be used by quantities for domestic and commercial area of dry ingredients per cubic, slump and much more and works for small jobs.
Here on testing is necessary just to place the ingredients accordingly to get the results you want for each concrete mix ratio.
