Half Cell Potential:
Measures the electrical current given off by corroding steelwork.
Carried out using equipment which satisfies the requirements of BS1881:Part 201 & ASTM C876.
To extract concrete cores for compressive strength tests.
Can also be carried out to provide pipework access.
Tests are made to accurately locate, orientate and measure the depth of cover over reinforcement bars using a an Electromagnetic Cover Meter.
For Chlorides, Sulphates & Cement content.
Involves removal of concrete dust samples for laboratory analysis.
Schmidt Hammer Testing:
A non-destructive method of testing the surface hardness of concrete.
To determine carbonation depth using phenolphthalein solution.
Break outs to expose steel:
For visual inspection of corrosion and to establish dimensions of steel reinforcement within concrete.
