摘要
该工艺是一种高吃灰率（≥85％）、高节能、简捷经济地用粉煤灰制造新型建筑材料—人造轻骨料的化学方法。
The present paper describes a chemical method for manufacture of ligbtweight aggregate from fIy ash. This new type buildiug material is composed or large proportion of fly ash,for example, 85 percent or more. The production process has many adventages such as higk energy-conservation,simplicity, economy, etc.
