Abstract :
The influence of Colloidal nano SiO2 (CNS) addition along with P-100 grade of fly ash on hydration of cement paste and compressive strength of cement mortar were investigated. The result revealed that fly ash hydration is accelerated by CNS at early age thus enhancing the early age strength of materials also it was observed that standard consistency of cement paste does not vary much more but by addition of CNS along with fly ash Initial and final setting time get accelerated, also the compressive strength of cement mortar was improved significantly.
