Strength And Durability Of Concrete: Effects Of Cement Paste-Aggregate Interfaces, Part I: Theoretical Study On Influence Of Interfacial Transition Zone On Properties Of Concrete Materials, Yiguo Zhang, Wai-Fah Chen Jan 1998

Strength And Durability Of Concrete: Effects Of Cement Paste-Aggregate Interfaces, Part I: Theoretical Study On Influence Of Interfacial Transition Zone On Properties Of Concrete Materials, Yiguo Zhang, Wai-Fah Chen

JTRP Technical Reports

This research was based on a two-part basic research investigation studying the effects of cement paste-aggregate interfaces (or interfacial transition zones-HZ) on strength and durability of concrete. Part I dealt with the theoretical study and Part II dealt with the experimental. Part I, the theoretical part, illustrates the effect of ITZ on the concrete properties by assuming its elastic moduli to be varied continuously in the region. A four-phase composite model is employed and three functions are chosen to model the moduli variation in the ITZ. A theoretical solution for an n-layered spherical inclusion model is used to estimate the ...
