Guestion is not correct - C 35/20. It will be C32/40, C10/15 ...(New Europan standarts, concrete class, from 2003 year) Here first 32 or 10 strength of concrete according with cylinder test result, 40 or 15 are strength of concrete according the cube result (N/mm2) For example C32/40 concrete class old C40 grade.

What is Grade of Concrete? Grade of concrete is defined as the minimum strength the concrete must posses after 28 days of construction with proper quality control. Grade of concrete is denoted by prefixing M to the desired strength in MPa. For example, for a grade of concrete with 20 MPa strength, it will be denoted by M20, where M stands for Mix.
