Abstract :

This study investigated the effect of using particle on nano- and micro- scale on the properties of cement mortar. Three types of fine powders, namely: nano-silica, silica fume and fly ash, were added to the mortar mix as a partial replacement of cement content by weight. A total of 64 mixes were screened using JMP program to obtain 12 optimum combinations of mixes in these mixes, the compressive strength, heat of hydration, atomic force microscopy, and XRD were measured in order to evaluate the effect of the above mentioned powders on the behavior of cement mortar. The outcome of this study showed that use of nano-silica with silica fume and fly ash significantly improves the compressive strength of cement mortar, as a result of their high reactivity with the residual CH from the hydration of cement and thus the formation of high content of C-S-H. This C-S-H was the responsible for the compressive strength improvement.
