Effect of nano silica on cement mortars containing micro silica
Challenge Journal of Concrete Research Letters, 2019 The use of cement and concrete is becoming increasingly widespread all over the world. However, the high energy consumption required for the production of clinker and the greenhouse gas emissions generated during production negatively affect both the economy and the environment.

Effects of Micro-silica and Nano-silica on Fresh Properties of Mortar
Materials Science, 2017 Like micro-silica (MS), nano-silica (NS) can also be considered as a supplementary cementitious material for production of high-performance mortar and concrete. To investigate the influence of MS and NS on the fresh properties of mortar or the mortar phase of concrete, an experimental program encompassing mortar mixes with various water, cement, MS and
