Description

Colloidal nano-silica was added to normal and fly ash concretes with different rates to examine the its effect on different concrete performance aspects. The main objectives of the study is to determine the effect of adding nano-silica on:

• The rate hydration and the reactivity of cement and pozzolans.

• The mechanical properties and strength gain rate (especially for fly ash concrete).

• Durability.

• Microstructure and Porosity.
