Aggregate sizes As described in BS EN 12620 aggregate sizes are expressed in terms of "d/D" with the guidance given in PD 66821 providing a table of recommended sizes that represent the best match to current production. Note that 4mm replaces 5mm as the break point between fine and coarse aggregate. For example, 20 5mm graded aggregate becomes 4/20.
calculate the median of the four results to two significant figures. Report the mean as the aggregate abrasion 812 : Part 113 : 1990 8. In this case repeat the test on two further specimens. remove the trays or backing plates and the weights and weigh the specimens to thc nearest 0.
