COMPUTERIZED CONCRETE QC USING SPREADSHEETS AND CUSUM GRAPHS

The articles compiled in this publication were written largely during 1987 and so are no longer the latest versions of the system described. However, they are still relevant today because they were not intended to provide readers with a ready-made system to copy and use as it stood. Rather, the purpose was threefold. One objective was to assist the non-computer-literate reader to learn to use Lotus 123. A second was to present new techniques of quality control and the third was to show how Lotus could be used to implement these techniques. This publication is therefore commended to the readers as a textbook on the use of Lotus 123 and on available techniques of concrete quality control. The first article explains how to set up a simple spreadsheet. The second explains five additional techniques: modifying spreadsheet layout; providing automatic statistics; drawing automatic graphs; interpreting a Cusum; and speeding result entry. The third article discusses database techniques. Article four deals with prediction of test results. In article five the question of how to analyze batch plant data is examined and the use of a printer is explained. The sixth article discusses automatic checking of compliance with specifications. The final four articles address, respectively, multiple grade spreadsheets, report preparation, regulating batch plants, and early strength of in situ concrete.
