摘要: Adsorption of N2 and water vapor was studied in completely hydrated tricalcium silicate fully from which Ca(OH)2 had been extracted. Compared with results obtained using N2, adsorption led to increased values for small-pore volume, peak shifts smaller sizes, decreased large-pore volume. Marked hysteresis observed the case adsorption; resorption branch apparently represents true pore structure. Extraction paste calculated volume small pores strikingly, suggesting that is hindered by Ca(OH)2; this tendency more obvious adsorption. The measurements indicate existence two kinds pores, i.e. a wider intergel-particle existing within gel particle. latter further classified into intercrystallite intracrystallite pores.
