Abstract: ABSTRACT:The influence of different superplasticizers on the hydration and textural characteristics of hardened pozzolanic cement pastes was evaluated. Thus, the BET surface areas and pore structures of hardened cement pastes containing different amounts of silica fume and/or various superplasticizers were determined via nitrogen adsorption isotherms measured at -196ºC. Three types of superplasticizers were used in this study, viz. naphthalene formaldehyde sulphonate (NFS), sodium gluconate (SG) and their mixt… Show more
