DPi & RBi pH Indicators
The DPI and RB9 Indicators are used to determine the depth of carbonation in samples of field concrete. Both indicators are supplied in special spray bottles. Carbonation depth can be used for the following purposes:
Uses
- To evaluate the cause of corrosion when conducting corrosion surveys
- To estimate service life where penetration of the carbonation front is critical
- To monitor the effectiveness of procedures for re-alkalization of the cover layer
- To make a rough estimate of concrete strength from the age of concrete and the relative humidity
