Sample Collection and Testing
The investigation into the extent of chemical contamination of concrete, likely to cause reinforcement corrosion, is a common requirement. Typically, concrete dust samples are extracted from representative structural elements to allow laboratory tests to be carried out to determine levels of chloride contamination, for example. |

Core Sampling and Testing
A number of methods exist to allow an assessment to be made of the in-situ strength of concrete. The most common method is to extract a concrete core sample from the structure under investigation and to carry out a compressive strength test in the laboratory. This provides an estimated in-situ cube strength. |
