Methods of obtaining pore solution from cement pastes

Nov 01, 2007  However, the elution method shows a greater sensitivity to mix composition (specifically cement content) than the pore solution expression method (Fig. 3, Fig. 6). Both methods show a decrease in chloride concentration as the water: cement ratio of the mix is increased. This effect is due to water being taken up during the hydration reaction.
