对混凝土用细骨料筛分试验方法的辨析.

By comparing and analyzing the current industrial standard JGJ 52—2006 Technical requirements and test method of sand and crushed stone (or gravel) for ordinary concrete, the current national standard GB/T 14684—2011 Sand for construction, and the international organization for standardization standard ISO 6274: 1982 Concrete—Sieve analysis of aggregates, combined with practical inspection experience, the research contents and suggestions on the test sieve used in the fine aggregate sieve analysis test method and the maximum allowable sieve allowance on a sieve surface in the sieve analysis process are put forward, so as to promote the progress of concrete fine aggregate sieve test method.
