| 1. | The hydration theory and the structure forming of hplc are analyzed through xrd , sem , edxa , and the analysis of pore structure , micro hardness . the model of the interface structure between lightweight aggregate and harden cement paste is divided into 4steps , which are penetrating , hydrating and hardening , diffusing of moisture and ion , forming of optimal interface structure , and the ideal structure model of lightweight aggregate is built
采用xrd 、 sem 、 edxa 、孔结构分析与显微硬度技术分析了高性能轻集料混凝土的水化硬化机理及结构形成过程，把轻集料与水泥石之间界面结构形成过程分为渗透、水化硬化、水分迁移与离子扩散、界面结构优化四个阶段，提出了轻集料与水泥石之间的界面结构模型和高性能轻集料的理想结构模型。 |
