Understanding Concrete Mix Grades: A Comprehensive Guide

Concrete grades represented as C16/20, C20/25, and C25/30 follow specific mix ratios. These representations indicate cube and cylinder compressive strengths, emphasizing the importance of understanding the distinctions between M and C grades.

Concrete grades

EC2 (1) uses the cylinder strength, fck, to define the concrete strength in design equations, although the cube strength may be used for control purposes. The grade designations specify both cylinder and cube strengths in the form C cylinder strength/cube strength, for example C25/30.
