Civil Engineering - Concrete Technology - Discussion

@All.

This discussion provides a straightforward confirmation of the standard nominal mix ratio for M10 grade concrete, referencing the IS code for validation and clarifying the parts of the ratio.

The thread serves as a good, quick reference for students and professionals seeking to memorise these essential concrete mix proportions used in construction.

The discussion page focuses on the M10 grade of concrete, establishing that its nominal mix proportion is approximated as 1:3:6 (Cement: Fine Aggregate: Coarse Aggregate).

This designation is based on IS 456-2000, where 'M' stands for 'Mix' and the number '10' represents the concrete's specified minimum 28-day cube compressive strength of 10 N/mm^².

The discussion confirms this standard and provides a general table of common nominal mix ratios for different grades of concrete (M-grades are specified by their characteristic compressive strength in N/mm²).

Here it provides a practical breakdown of concrete grades that is very useful for engineering students. It is interesting to see how contributors use simple arithmetic tricks to help others remember complex structural ratios.
