编者的话粉煤灰硅酸盐砌块是我国六十年代初独自发展起来的新型建材制品,这种利用工业废渣为原料生产的砌块,至今已形成相当规模的生产能力。但二十多年来,对于粉煤灰硅酸盐制品生产配合比设计问题,尚无系统研究和制定配合比设计的正规方法,多年来一直沿用试配法定值,无法试配具有一定强度和收缩值的硅酸盐砼,使蒸养硅酸盐制品的发展受到了一定的限制。为此,国家建材局于1983年下达了粉煤 The editor’s words fly ash silicate block is a new type of building material product that was independently developed in China in the early 1960s. This type of block, which uses industrial waste as raw material, has formed a considerable scale of production capacity. However, over the past 20 years, there has been no systematic study on the design of mix proportions for fly ash silicate products. The formal method for designing mix ratios has been used for many years. Shrinkage silicates have limited the development of steamed silicate products. To this end, the National Building Materials Bureau issued pulverized coal in 1983.
