Practical Grading of Aggregates Concrete Technology

2 天前  Four curves are shown for each maximum size of aggregate, but due to the presence of over and under size aggregate and also due to variation within any fraction size, practical gradings may be in the vicinity of these curves than to follow them exactly. Therefore it is convenient to specify grading zones rather than a single curve.
