6. Adhesion at the interface between concrete and paint
6.1 Analysis of concrete and paint surfaces
Concrete samples were characterized 28 days after demolding by IR spectroscopy (in ATR mode) to compare surface composition according to the mold used (PVC or POM molds). Table 5 shows the IR bands of concrete (PVC mold): portlandite (at 3,640 cm- 1 ), which is one of the major hydrates formed during concrete hardening, is thus easily detected.
The band at 1080 cm- 1 corresponds to the sum of several peaks characteristic of silica and hydrated calcium silicates (C-S-H). In addition, three high-intensity bands correspond to CaCO 3 ...
