MODIFICATION OF THE FORMULA USED IN THE .MODIFICATION OF THE FORMULA USED IN THE DETERMINATION OF THE TEN PER CENT FINES VALUE OF AGGREGATE. One established method of estimating the force required for the ten per cent fines test on an aggregate is to divide the number 4000 by the aggregate impact value. However recent analysis of ten per cent fines and aggregate impact data for 79 aggregate samples of various rock .Effect of curing method on characteristics of .For aggregates whose crushing value is above 25% (Neville, 2000), 10% fines value (TPFV) is recommended by BS for relative measure of strength. Hence the strength of fly ash aggregate was determined through 10% fines value as per BS , on 12.5–10 mm size aggregates.

Building Materials Laboratory ManualThe test results should be compared with the standard values and conclusion should be drawn. Building Materials Laboratory Manual Fall 2007 -2008 Prepared by: B. J. Farid 2 Reducing Field Sample of Aggregate to Test Sample ASTM C 702, D7 5 Purpose: To obtain laboratory samples of aggregates from stockpiles. Equipment : Shovel, scoop, boom. Procedure: 1 -Obtain a sample of aggregate .

European Aggregate Sizes - Northstone MaterialsTo complicate matters more, for fine and all-in aggregate, where D <= 8mm, the standard requires producers to declare a "typical grading", which, where required, must be within a given Tolerance Category designated according to a set ± value on the D/2 sieve, i.e., G TC 10, G TC 20 or G TC NR (no requirement). A typical quarry dust could be designated 0/4 G A 85 G TC 20.

Numeric arguments 2 to 253 for which you want the aggregate value. For functions that take an array, ref1 is an array, an array formula, or a reference to a range of cells for which you want the aggregate value.
