Gas sorption surface area measurements have been important for developing microstructural models for the structure of calciumsilicate-hydrate (C-S-H), the major hydration product of portland cement. However, surface area measurements using the nitrogen BET method have historically had high variabili

Portland blast-furnace slag cement pastes were prepared with various water/cement ratios. Specific surface areas and pore structures of the hardened pastes were investigated by nitrogen adsorption. The "accessibility" of the nitrogen molecules to the pore structure is discussed in terms of degree of

The diffusion and sorption behaviour in disc shaped samples of hardened cement paste (HCP) has been studied for the radionuclides C1-36, 1-125 and Cs-134 using the through-diffusion technique. The experiments were performed both in controlled atmosphere glove boxes (Pco2 = 10-5.Sbar) and under atmos

Miniature, saturated, hardened cement paste specimens were pretreated for 2 days at various temperatures in the range 20-92ยฐC. Specimens were then loaded for 6 days and unloaded; immediate, creep and recovery strains were monitored, as were changes in the microstructure --polysilicate and nitrogen $
