Modelling of nano-silica in cement paste

Abstract

Recently published experimental evidence shows that nano-silica is a material that can be used to enhance the strength and durability characteristics of concrete. Engineered concrete at the nano-scale is achieved through the integration of nano-materials in suitable proportions and relevant mixing methods. Being a pozzolanic and reactive material along with nucleation effects and miniature particle size, nano-silica has been found to significantly improve the micro-structural characteristics of concrete making it denser and more uniform. The ongoing research work at the University of Melbourne is based on a novel modelling approach to further investigate the performance characteristics of na..
