Concrete strength development
Coordination between structural engineer
and construction contractor
Basics
Starting in 2005, the development of concrete strength (Fig. 1) has increasingly been the subject of standardization. This trend began as early as with the 2001 DIN 1045 series [1, 2, 3], followed by [4]; [5] and [6] ensure that concrete strength will continue to play a key role in European codes and standards. The term “development” clearly indicates that the various points in time during the construction process (associated with varying concrete compressive strengths) have an influence on different aspects of construction. However, these points in time/concrete ages (referred to as A,...
