In this paper. the effects of different aluminum to silicon ratios in silicate chains of calcium silicate hydrates (C-S-H) are evaluated on the diffusion coefficient of chloride ions by molecular dynamics method. Tobermorite is a crystalline phase that is used for studying C-S-H properties in nano scale. because of its analogous chemical composition to C-S-H. https://www.indiamapdigital.com/product-category/women-polo-shirt/
