aggregate crushing value bs812 part 3

Mechanical Properties of Aggregates Aggregate Crushing Value Test (BS:812, part 3) Procedure • The material to be tested should pass a 14.0 mm (1/2 in.) sieve and be retained on a 10 mm (3/8 in.) sieve. • Dry the sample in an oven at 100-110 0 C for four hours. • Place the sample in a standard cylindrical mould and tamp it

BS 812: Part 3 specifies a maximum limit of 30 for aggregates used in structural concrete and 40 on aggregates used in lean concrete. • For crushing values of over 25 to 30, the test is insensitive because the weaker material is crushed before the 400 kN load is reached and compacted in a manner that further crushing is reduced. For such materials, a ten percent fines value test is suggested by BS:812, Part 3
