Feb 01, 1991 C. D. Gribble writes I read the technical note by J. C. Bullas with interest. He discusses the value of K used to estimate the value of force in kN which must be applied to a sample of aggregate to obtain ten per cent fines in the expression Force kN K AIV. The reduction he suggests in the value of K from 4000 to 2800 is based upon samples of crushed rock aggregates, i.e. all the ...

The Fineness Modulus is used in US practice and is a measure of the grading of fine aggregates. It can be calculated from a sieve analysis by adding the cumulative percentages of fine aggregates retained on the following sieve sizes 0.15mm, 0.30mm, 0.60mm, 1.18mm, 2.36mm and 4.75m. This value is then divided by 100 to give the fineness modulus.
4.1 Some contract documents specify certain aggregate sizes for specic uses or may suggest one or more of these sizes as appropriate for the preparation of various end-product mixtures. In some cases, closer limits on variability of the aggregate grading are required. 5. Manufacture 5.1 The standard sizes of aggregate described in this clas-
