Scaling of 205 days old concrete without ConcreCem after 28 freeze/thaw-cycles

with 0,3% ConcreCem after 28 freeze/thaw- cycles
Figure 8.5: Amount of scaling of the concrete with and without the addition of 0,3% ConcreCem
The addition of ConcreCem provides enhanced durability. This cannot easily be calculated and expressed in hard currency. It remains very difficult to calculate the costs of repairing concrete in which no ConcreCem was used. For instance the damage caused by freeze-thawing as shown in this chapter. The use of only 0,3% ConcreCem will reduce freezing-thawing damages fivefold!
For us the question remains how can we calculate these benefits, however the customer or authority faced with the annual repair bill can quickly make this calculation!
