(一)前言蒸养粉煤灰硅酸盐制品,国内已经普遍应用多年,对其中水化产物的研究虽然作了不少工作,但仍然不够。尤其是对其中主要的水化产物——水化硅酸钙的形态及组成,许多都是根据理论推导或间接证据,缺乏直接证据。我们为了进一步弄清蒸养粉煤灰硅酸盐制品中水化产物的组成 (I) Introduction Steam-fed ash silicate products have been widely used in China for many years. Although much work has been done on the hydration products, it is still not enough. Especially for the main hydration product, the morphology and composition of calcium silicate hydrate, many of which are based on theoretical derivation or indirect evidence, lacking direct evidence. In order to further understand the composition of the hydration products in steamed fly ash silicate products
