Abstract

In this study, the effect of fineness and grain size distribution of the cement used in the source concrete from which the recycled materials were obtained and its water/cement ratio on the pozzolanic activity of recycled mortar powder were investigated. The specimens, whose strength values were determined, were first ground to a small size with the help of a jaw crusher and then ground into powder in a ball mill. The usability of the powder material passing through the 0.075 mm sieve as a binder was investigated. It was determined that the pozzolanic activity index of the recycled powders varied between 54% and 84%.
