Study on the Structural Model of Calcium Silicate Hydrate based on Computer Simulation

Calcium Silicate Hydrate (C-S-H) is the main hydration product of Portland cement, it has an important impact on the properties of cement and causes a wide range of study. In recent years, superplasticizer, of which the main component is organic macromolecules, has become an important component in preparation for high performance concrete. Molecular dynamics simulation of cement hydration products were summarized, the simulation of hydration process of cement paste and the formation of microstructure were introduced and model of calcium silicate hydrate mixed with superplasticizer were studied in this paper.
