Apr 26, 2018· Procedure forcrushing strengthofaggregate. Before testing, theaggregateshould be in surface dry condition.You can achieve the dry condition ofaggregateby placingaggregatesin an oven for 4 hours at 100-degree Celcius. Theaggregatespassing through 12.5mm and retained on 10mm IS sieves are selected for findingaggregate crushing strength
