CST Corporation propose a proof of concept project to develop basic prototype device of a new ConcTest, which will allow rapid and accurate prediction of ‘wet’ concrete strength. Manufacturers and users of concrete products experience issues due to the requirement to wait 28 days until the cured product can be tested for strength. Also if the poured concrete falls below the specification, costly remedial work is required; this leads to manufactures relying on costly over-specified formulations. We intend to build and test a prototype device based on our patented methodology. The device will be able to quickly and accurately predict the eventual strength of concrete before pouring, reducing delays and cost. The device is unique and removes the need for batch sampling; for the first time all batches of concrete can be checked that they meet the required specification.
