QUALITY CONTROL OF CONCRETE AND ITS ECONOMICS FOR PAVING PROJECTS

THE VARIOUS FACTORS CONTRIBUTING TO THE VARIABILITY IN THE QUALITY OF CEMENT CONCRETE ON PAVING PROJECTS ARE DISCUSSED AND SUITABLE CONTROLS TO REDUCE THEM ARE SUGGESTED. REFERENCE IS MADE TO COARSE AND FINE AGGREGATE, BATCHING, MIXING, COMPACTION, CURING AND TESTING, WHILE DETAILS OF STRENGTH DATA AND THEIR ANALYSES ARE PROVIDED. IT IS RECOMMENDED THAT BOTH FOR ROAD AND AIRFIELD PAVEMENTS THE PROBABILITY VALUES OF ONE IN TEN MAY BE SPECIFIED. IT IS ALSO RECOMMENDED THAT WITH GOOD QUALITY CONTROL A COEFFICIENT OF VARIATION OF 15 PER CENT MAY BE ASSUMED FOR THE INITIAL DESIGN OF THE CONCRETE MIX IN THE LABORATORY. /RRL/
