What is the size of coarse aggregate used in concrete ...

Generally the size of coarse aggregate used is 10-12.5 mm. If we use the proportional mix of different sizes small to large (>4.5 mm to 20/25 mm), this make the concrete structure compact by align themselves in voids depending upon their size and compact mass will be formed with increased strength.
