Heats as well as entropies of water and nitrogen adsorption on hardened cement pastes of various pore structures were computed. Water vapor adsorption is accompanied by a decrease in integral entropy relative to the liquid state, while nitrogen adsorption Ls accompanied by an increase in integral en

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
