  • Patent number: 8534118
    Abstract: Methods and apparatus are presented for quality control of a process to produce concrete goods products. The quality control is effected on the basis of measurements that are carried out on the concrete goods products in an intermediate step of the process after shaping and compacting in the fresh concrete phase. Measurement values are determined on a test fresh concrete product from the intermediate step of the process, which measurement values comprise a measure of the bulk density and the gas permeability of the test fresh concrete product. Subsequently, an estimated value for a quality measure of the hardened concrete product is determined on the basis of a predetermined predictive model. The predictive model 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.
