Control unit for assuring the qualityof paving stone production

QAVER®tec GmbH, Flensburg; products for checking concrete


The Qaver (= Quality for Paver), the new checking appliance for assuring the quality of concrete goods, had already convinced a few months after its successful market introduction due to its versatility and reliability. The Qaver was developed as a measuring instrument for fresh concrete goods, in particular paving stones, in order to specifically enable the measurement and evaluation of the quality of compaction of the facing and core concrete as well as the gross density and dimensional stability of the product directly after production. The measuring unit is complemented by an external evaluation program, which is employed in combination with the measurement results from the Qaver as a uniform quality assurance system. This means: the consistent use of the measuring instrument to measure the physical characteristics of concrete blocks directly in the plant, combined with the specially developed program for evaluating the measurement data in the laboratory, provides the manufacturer for the first time with a tool for optimising production parameters and sensitising the personnel on the machine. Furthermore, Qaver offers possibilities to extract the optimum savings potential from mixture recipes, in particular where binding agents and/or other substitutes are concerned. The Qaver is considered to be unique in the world with this overall concept.
