Abstract:
Modern statistical techniques are particularly valuable in the concrete quality control system because of the many variables involved and the repetitive individual batch method of concrete production, The twin advantages of greater economy and improved structural integrity offer a substantial benefit to the user of such methods. Widespread availability of small computers makes these controls even more attractive. Specific applications include statistical routines for measures of central tendency, measures of variability, and linear regression analysis applied to water-cement/strength ratios and prediction of future strengths.
