Concrete ballpark values for structural engineers

Separating the requirements for concrete structures into at least three different sets of applicable guidelines and standards for structural design, concrete production and construction has resulted in each of the parties involved knowing more or less only “their” part, the connecting points being frequently lost.

It is obvious that the exposure classes specify the maximum water-cement ratio, but with the CEM II/A … 42.5 N cements commonly used today, this – even unintentionally – leads to compressive strengths that are often far higher than the structurally required values. Table 1 shows the...
