10 rows The test conducted to know the compressive strength of aggregate is known as aggregates crushing value test. The crushing value of aggregates is rather insensitive to variation in strength of weaker aggregates. For this reason a simple test known as 10 percent fine value is introduced. When the aggregates crushing value become 30 or higher the results are likely to be inaccurate.
