Concrete Testing is one of DPC LTD’s key activities, and is critical to ensure concrete is fit for purpose and meets required specifications. We can provide the following tests –
Carbonation tests
After breaking out as specified the exposed surface of concrete shall be tested for carbonation by the use of a semi-aqueous solution of phenolphthalein. The tests shall be carried out on the freshly exposed concrete or at least within 30 minutes of being exposed.
Chloride tests
Samples of concrete will be sent for analysis at one of our laboratories. Where it is determined that risk levels of chlorides are present in the concrete, the agreed area(s) shall be broken out to remove all contaminated concrete or having regard to the steel reinforcement, to a depth as directed by the main contractor.
Hammer Testing
A Schmidt hammer will be used to find out the compressive strength of the concrete. In order to minimise the local variation in any samples taken a selection of readings (9 in total) will be recorded giving an average value.
Crush & Cube Testing
The concrete crush and cube test is an effective test to determine the compressive strength of concrete. Samples are taken from the concrete cured under standard conditions and crushed to determine the maximum compressive strength in our UKAS accredited laboratory.
Once the above tests have been completed the results will then be compiled into a report for your records. Clearly illustrating any weaknesses in the concrete or dangerous levels of contamination which may be present.
