the ‘ impact ’ is the mean of two observations, rounded to a nearest whole number. precautions place the plunger centrally so that it falls directly on the sample and does not touch the wall of the cylinder in order to ensure that the entire load is transmitted on the aggregates.
the ‘ ` gives a relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load. is defined as the percentage by weight of the crushed (or finer) material obtained when the are subjected to a specified load under standardized conditions, and the strength of the …
