coarse being described as gravel or crushed rock and fine being described as sand.Aggregate consists of particles of a rock it is a material more refining process.Aggregate crushing Value =(W B /W A) × 100 Record. The mean of the two results is reported to the nearest whole number as the aggregate crushing value of the tested material. Safety & Precautions: Use hand gloves while removing containers from oven after switching off the oven. To wear safety shoes & helmet during the time of test.Aggregate impact value (%) = ( W 2 /W 1)×100. Comments: The classification is made through: Aggregate impact value: Classification 35%: Weak for surfacing: The comments can be made on the basis of the results obtained. Precautions: The hammer should be dropped freely. The drop height ...Aggregate impact value = W 2 W 1 (100) 10.33% Aggregate impact value = W 2 W 1 (100) = 37.3 36 (100) = 10.33% pg. 9 Precautions: 1. Place the hammer centrally so that it falls directly on the aggregate sample and does not touch the wall of the cylinder to ensure that the entire load is transmitted on the aggregates.• At $76,
