Combined production and conformity control of concrete

Production and conformity control are most often used as separate tools in the quality control process of concrete production However, both methods can be combined in a way so that conformity control is used as a steering element for the production process This paper describes a methodology for the design of appropriate Vmasks for cusum control charts in case of a combined production andControl Chart Basics A control chart consists of a time trend of an important quantifiable product characteristic In addition to individual data points for the characteristic, it also contains three lines that are calculated from historical data when the process was “in controlHow To Use Control Charts To Improve ManufacturingThe important characteristics of aggregates for concrete are listed in Table 52 and most are discussed in the following section: Grading Grading is the particlesize distribution of an aggregate as determined by a sieve analysis (ASTM C 136 or AASHTO 80 Design and Control of Concrete Mixtures EB001 Table 51 Rock and Mineral ConstituentsAggregates for Concrete Memphis
