Proportions for different grades:
Cement : Sand : Gravel
1 : 2 : 5 for grade C15(general purpose concrete) 15 mpa
1 : 2 : 4 for grade C25(strong) 25 mpa
1 : 2 : 3 for grade C30(very strong) 30 mpa
Remember the proportion is done in terms of volume. This means the above proportions are
correct if using the same measure.
