The specific surface of hardened cement paste by small-angle X-ray scattering effect of moisture content and chlorides
AbstractThe specific surface of hardened cement paste (hcp) at relative humidities (R.H.) between 0 and 100% has been investigated by small-angle X-ray scattering (SAXS). On desorption from 100 to 40% R.H., a reversible 35% decrease in measured specific surface occurs. This is interpreted as the action of the disjoining pressure in small gel pores. Measurements on samples subjected to chloride action in aqueous NaCl solutions showed little change below 60% R.H.. At higher humidities the specific surface increases uniformly with NaCl concentration.
