轻集料混凝土界面研究

Research on Lightweight Aggregate Concrete Interface

介绍了轻集料混凝土的界面进行三维重建以及计算界面的分数维表征其粗糙度的方法,述评了轻集料混凝土的立方体抗压强度、劈裂抗拉强度和抗折强度与轻集料混凝土界面分数维的相关性,以及界面分数维与界面粗糙度、界面的啮合结构、界面黏结力的关系。

The 3d-reeonstrnction for interface about lightweight aggregate concrete was introduced, as well as the methods which characterize the concrete roughness by calculating interface fractional dimension. The result revealed the relativity between mechanical properties （ineluding compressive strength, split--tensile strength and flexural strength） and the interface fractional dimension of light weight aggregate eonerete. Moreover, the relationship between the interface fractional dimension and the interface roughness, the interface joggle strncture, interface bonding strength was also showed.
