ABSTRACT
Conformity control is often used in order to verify whether the delivered product, i.e. concrete, complies with the specifications. Due to this quality control, certain batches of concrete are accepted and some are rejected, resulting in a filtering effect with respect to the concrete strength distribution. As a consequence, conformity control increases the achieved safety level in comparison to production without conformity verification. Further, also the dependency of the reliability index with respect to parameter uncertainties reduces due to the quality verification, resulting in an increase of the predictive reliability index.
