TESTING AGGREGATES. PART 105: METHODS FOR DETERMINATION OF PARTICLES SHAPE. SECTION 105.2: ELONGATION INDEX OF COARSE AGGREGATE

This Section of BS 812 prepared under the direction of the Cement, Gypsum, Aggregates and Quarry Products Standards Policy Committee, is a revision of 7.4 of BS 812: Part 1 : 1975 which will be deleted by amendment. Part 105 comprises two separately published sections: 105.1 Flakiness index of coarse aggregate (see IRRD 828491), and this Part. A method is described for determining the elongation index of coarse aggregate. The associated tests for angularity number given in the 1975 edition of BS 812 : part 1 is no longer included in this revision because of lack of use. For the purposes of this Section, the definitions given in BS 812 : Parts 101 and 102 apply. For the abstracts of other parts of this standard see IRRD nos: 269286-269288, 229682, 278567, 823951, 285407, 823308, 828491, 285409, 823309, 285410, 823310, 823664-823665. (TRRL)
