Abstract
Nano-silica and its use in cement-based materials, especially concrete, has been the focus of many scientific studies. This is
because cement production is an energy-intensive process and because concrete is the most used construction material worldwide.
Accordingly, it is very important to understand the complexity of concrete, improve its performance and durability. This paper
reviews the existing literature on the effects of nano-silica on concrete mechanical properties, microstructure and cement hydration.
