日本工业标准（JIS）“用于混凝土的粉煤灰，JIS A 6201”于1999年修订，以扩大粉煤灰作为矿物掺合料的可利用量。此次修订的特点是：[1]将烧失量（LOI）在5.0%~ 8.0%范围内的高飞灰规定为III类，[2]将Blaine细度在1500 cm 2/g ~ 2500 cm 2/g范围内的低飞灰规定为IV类，[3]将LOI小于3.0%且Blaine细度大于5000 cm 2/g的优质飞灰规定为I类。在JIS A 6201-1996中合格的大部分飞灰将被指定为II类。III类和IV类粉煤灰不能满足JIS A 6201-1996的要求。本文介绍了JIS A6201标准修订的背景和内容.
The Japan Industrial Standard (JIS) of "Fly Ash for Use in Concrete, JIS A 6201", was revised in 1999 in order to widen the utilizable amount of fly ash as a mineral admixture. The featured points in this revision were that :[1] fly ash with high loss on ignition (LOI) ranging from 5.0% to 8.0% is specified as Class-III, [2] fly ash with low Blaine fineness ranging from 1500cm2/g to 2500cm2/g is specified as Class-IV, [3] high quality fly ash with LOI less than 3.0% and Blaine fineness more than 5000 cm2/g was specified as Class-I. Most of the fly ash qualified in JIS A 6201-1996 would be specified as Class-II. Class-III and Class-IV fly ash wouldn't meet the requirements of JIS A 6201-1996. This paper describes the background and the contents of the revision of JIS A 6201.
