Crushing force, F' (N) is given by F' _= bg, where b is the balance reading (in kg), and g = 9807 m s 2 is the acceleration due to gravity. Crushing method for intermediate aggregates For aggregates of 320 mm diameter which require crushing forces in the range 120 kg (10200 N), the lever loading method shown in Fig. 3 is very useful.

Apr 10, 2012· Aggregate Crushing Value. * The value is higher when more percentage of aggregates crush and break into smaller pieces which indicates the aggregates are of a lower quality. * Aggregate crushing value < 45% for aggregates used for concrete for non wearing surfaces and <25% for wearing surfaces like runways and roadways.
The crushed aggregates (W2) is expressed as % of the total weight of sample (W1), which is the crushing value of the aggregate. Aggregate crushing value = (W1/W2)*100. Recommended Values: In aggregate crushing test, if aggregate crushing value is less than 10, it signifies an exceptionally strong aggregate. SERVICE ONLINE LIVE CHAT

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.
