The implementation of nanotechnology in concrete has led to an active incorporation of nano silica in concrete in a global level. Different methods of nano silica production are available and vary from expensive to cost-effective routes. Nano silica particle sizes and their chemical and physical nature depend on the method of production. Several types of dispersed nano silica are recommended to be used in concrete due to practical reason. However, the dry powders of nano silica particles are difficult to be dispersed in concrete and require special types or family of nano superplasticizers. The effective addition of nS leads to C-S-H with improved cementitious properties.
