混合型粗集料轻混凝土的微观结构(Ⅱ)

Microstructure of Mixed Type Aggregate Lightweight Concrete (Ⅱ)

在混合型粗集料轻混凝土的微观结构 (Ⅰ )对早期水化产物和结构特点进行全面分析和论证的基础上 ,进一步对后期的水化产物和结构特点进行了系统的研究和论述 .同时 ,对陶粒 -水泥石界面与碎石 -水泥石界面的微观结构进行了分析和类比 .并提出 ,在两种不同的界面处 ,分别存在着不同的水化条件和水化产物 。

Based on comprehensive analysis and demonstration to its early hydration product and structural characteristic in microstructure of mixed type coarse aggregate lightweight concrete,the paper researched and expounded on its correspondent final hydration product and structural characteristic.In addition,the interface microstructure of the ceramisite-hardened cement paste and the crushed stone-hardened cement paste are analysed and compared.We put forward the idea that there are different hydration conditions and hydration products in both different interfaces,and they demonstrated various microstructure forms.
