The classification C35/C45 refers to the compressive strength of the concrete, with C35 indicating a strength of 35 MPa for 28-day cube tests, and C45 indicating a strength of 45 MPa for 28-day cylinder tests. Let's explore what goes into making this specific type of concrete and why these components are crucial. What Makes C35/C45 Concrete ...
