SUGGESTIONS FOR THE INTERNATIONAL STANDARDIZATION OF TEST METHODS FOR AGGREGATE STRENGTH

It is suggested that the Los Angeles method according to ASTM C 131 is recommended by the Rilem-Committee as the main test method. As a single standard fraction grading B appears to be the most suitable one. Tests on other fractions should be avoided. If the committee consider it necessary, some supplementary tests (crushing and impact type) may be included in the recommendation. In order to make it possible to test "local materials" the French "micro deval" method should be adopted for dry and wet samples. The wet abrasion is the most important procedure. There is, for the time being, no accepted method for the testing of aggregate homogeneity. The brass rod scratch test (ASTM C 235) appears to be a suitable method for determining the content of very soft pieces in aggregates. /TRRL/
