Weak aggregates may break down during mixing, handling and compaction. Within British Standards, the mechanical properties of aggregate can be assessed from 10 per cent fines value or aggregate impact value. In the 10 per cent fines test, a load is applied to the 14–10 mm fraction of the aggregate.The test sample must be aggregate that passes a 12.5 mm IS Sieve and is retained on an 10 mm IS Sieve. The aggregate comprising the test sample must be dried and cooled in an oven for four hours at a temperature of 100 to 110°C. Fill the measure roughly one-third full with aggregate and tamp with 25 strokes of the rounded end of the tamping rod.Aggregate Impact Value Test (AIV) - CivilYardProcedure of Aggregate Crushing Value. Take a sample of aggregates by sieving through 12.5mm and retained on 10mm. The aggregate shall be tested in dry surface conditions. If dried by heating, the period of drying shall not exceed 4 hours and temp shall be 100-110 deg C.Lab Test on Aggregates at Site - CivilJungleاحصل على السعر
