As famed quality control expert Dr. W. Edwards Deming would say, Quality is not so much an outcome as a neverending process of continually improving the quality of what you produce. This means that the work teams at the quarry need to inspect the yard daily, check the pile, and check primary, secondary and tertiary crushing and screening
Depending upon the type and size of the coarse aggregate, it may be necessary to reduce the coarse aggregate content from 5 to 10 percent as compared to mixtures placed by conventional methods. 4. Fine aggregate. The properties of fine aggregates are more critical in proportioning pumpable mixtures than are the properties of the coarse aggregates.
Yet, the quality and control of these gradations is absolutely essential to the workability and durability of the end use. Gradation, however, is a characteristic that can be changed or improved with simple processes, and is the usual objective of aggregatepreparation plants.
