Abstract
The issue of accuracy in calculation of concrete compressive strength, especially for a maturity period longer than 28 days, is useful in some calculations during designing concrete structures. The MC 2010 pre-standard and the PN-EN 1992-1-1 standard provide the equation for calculations of fcm(t) including material ratio is dependent only on the strength class of cement. The paper evaluates accuracy of this approach with the example of a large set of research results for concrete of varied level of strength and quality of cements.
