Quantification of Pore Size Distribution Modification Due to Metakaolin Inclusion in Cement Based Systems
Abstract Hydraulic cement based composites in general and concrete in particular reveal different spatial heterogeneity at different scales. At macro engineering scale, e.g., meter or decimeter scale, the material is considered as isotropic and homogeneous, at a lower scale they are two phase material with aggregate particles dispersed in a matrix of the cement paste. One may also consider a third phase called interfacial transition zone (ITZ) at the interface of aggregate and paste. If one looks at cement paste itself at a finer level, it is heterogeneous at micro level, characterized by solid product of hydration reaction, un-hydrated cement, gel and capillary pores. At still finer atomistic level one may encounter further heterogeneity as well, in structure of the material.
