Abstract

This paper has been researched that the earlier compressive strength of the cement pastes containing nano-TiO2 particle curing 1day, 3days and 7days. For the compressive strength measurements, all samples(dimensions 50×50×50mm) were prepared in accordance with ASTM C109. The compressive strength of the specimens with nano-TiO2 at the early age(1day, 3days and 7days) stage was lower than that of the reference group. Therefore, nano-TiO2 has little positive effect on the improvement of the compressive strength of cement pastes during early ages.
