aggregate crushing value bs812 part 3

value 7.1 General. The aggregate crushing value gives a relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load. With aggregate of an aggregate crushing value higher than 30 the result may be anomalous, and in such cases the ten per cent fines value (clause 8) should be determined instead

    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
