A HYDRATION MODEL OF AGGREGATE-MORTAR TRANSITION ZONE CONSIDERING PORE-PERMEATION COUPLING EFFECT BASED ON FRACTAL THEORY

ABSTRACT
The high and non-uniform distributed porosity of the interfacial transition zone affects the macroscopic properties and failure behavior of concrete significantly, and it relies on the non-uniform water-cement ratio and pore-permeation coupling effect during hydration. However, current hydration models could not reveal the above facts. In this paper, water-cement distribution is derived, pore-permeation coupling effect is introduced based on fractal theory. Finally, a hydration model of the interfacial transition zone is established. A good agreement between the porosity prediction of interfacial transition zone and experimental data is found.
