Statistical comparison of data from concrete families in ready-mixed concrete plants

摘要

Data has been collected from several European ready-mixed concrete plants in order to analyse some data-based statistical aspects of the concrete family concept. Concrete strength records of concrete families were obtained from seven different concrete plants. This data is used to investigate the presence of autocorrelation in the transposed data of concrete family strength records. Further, strength records from two Belgian concrete plants are investigated in more detail and used to investigate how the concrete family concept, the applied transformation method and the family composition guidelines influence the general quality of accepted batches.
