In aggregate crushing value test, the aggregate is subjected to 400 KN compression load in a cylindrical mold. The crushing value is defined by the percentage loss in mass on mm size of test. Bigger percentage of aggregate crushing value means the aggregate is inferior in quality. According to BS 882:1992, aggregate with crushing value less

· Aggregate crushing value is defined as the percentage by weight of the crushed (or finer) material obtained when the test aggregates are subjected to a specified load under standardized conditions, and the strength of the aggregate used in road construction is expressed by numerical index. Aggregates with lower crushing value show a lower ...
Mechanical Properties of Aggregates Aggregate Crushing Value Test Discussion • There is no explicit relation between the aggregate crushing value and its compressive strength but, in general, the crushing value is greater for a lower compressive strength. BS 812: Part 3 specifies a maximum limit of 30 for aggregates used in structural concrete and 40 on aggregates used in lean concrete.
Advantages Of Aggregate Crushing Value PANOLA Mining machine.

Aggregate crushing value test on coarse aggregates gives a relative measure of the resistance of an aggregate crushing under gradually applied compressive load. Coarse aggregate crushing value is the percentage by weight of the crushed material obtained when test aggregates are subjected to a specified load under standardized conditions.
· This percentage is known as a crushing value of aggregate. This percentage should not exceed 30% of the total weight of aggregate taken for the test. The aggregate crushing value test result should not be more than 30 % for the concrete used for roads and pavements and, in case of other structures; it may be permitted up to 45%.

Aggregate crushing value test on coarse aggregates gives a relative measure of the resistance of an aggregate crushing under gradually applied compressive load. Coarse aggregate crushing value is the percentage by weight of the crushed material obtained when test aggregates are subjected to a specified load under standardized conditions.
· Aggregate impact value test gives an indiion of aggregate's toughness property ( property of a material to resist impact) Aggregate impact values are used to classify the stone aggregates with respect to toughness property as given below. Aggregate impact value (%) Toughness Properties <10 Exceptionally tough / Strong 10 – 20 Very tough / Strong [.]
· Aggregate Crushing Value. Introduction. The principal mechanical properties required in stones are satisfactory resistance to crushing under the roller during construction and adequate resistance to surface abrasion under traffic. Aggregates used in road construction, should be strong enough to resist crushing under traffic wheel loads.
