Freeze-thawing tests are also performed to concrete of 205 days old, with and without the addition of ConcreCem. Except for the amount of ConcreCem both mixes have an identical mix design.
As can be seen in the following pictures, the concrete with 0,3% ConcreCem has clearly fewer scaling than the concrete without ConcreCem.
The concrete without ConcreCem had a weight loss of 3,6 kg/m2 , whereas the concrete with 0,3% ConcreCem had a weight loss of a marginal 0,7 kg/m2 only.

Figure 8.3: Surface of 205 days old concrete without ConcreCem Figure 8.4: Surface of 205 days old concrete with after 14 after 14 cycles of Freeze-thawing 0,3% ConcreCem after 14 cycles of Freeze-thawing
After 28 cycles the mass of scaling is also measured and figure 8.5 shows the amount of scaling of the concrete with and without the addition of 0,3% ConcreCem. The difference in the amount of scaling is really huge!
