Abstract:
1. A method for quality control of a process for producing concrete goods products, wherein the quality control is carried out on the basis of measurements that are performed on the concrete goods products in an intermediate step of the process after shaping and compacting in the fresh concrete phase, wherein the method comprises: determining measurement values on a test fresh concrete product from the intermediate step of the process, wherein the measurement values comprise a measure of the bulk density and the gas permeability of the test fresh concrete product, and determining an estimated value for a quality measure of the hardened concrete product, that results in the further course of the process from the test fresh concrete product, on the basis of a predetermined predictive model that relates the measurement values of fresh concrete products from the intermediate step of the process to the quality measure of the corresponding hardened concrete products.
