规定了通过筛分测定粗骨料和细骨料粒度分布的方法。当样品在75 m筛上洗涤时，可使用该方法测定通过75 m筛的量。如果规定了通过75m筛的材料百分比，则本方法第6.6条或AS 1141.12中详述的程序适用。关键词:骨料；微粒大小筛选。

Sets out method for the determination of particle size distribution in coarse and fine aggregates by sieving. The amount passing a 75 μm sieve may be determined using this method when samples are washed over a 75 μm sieve. If the percentage of material passing a 75 μm sieve is specified, the procedures detailed in Clause 6.6 of this method or in AS 1141.12 apply. KEYWORDS: Aggregates; Particle; Size; Sieving.
