Abstract:
The influence of ethyl-alcohol and 1–4 dioxane on the rheological properties and hydration of portland cement paste have been studied. The rheological properties are correlated to the cement/liquid interface characteristics. The relationship between viscosity and zeta-potential is discussed. Analyses of the liquid phase composition and conduction calorimetric measurements have been made to quantify the retardation effect of organic solvent on the cement hydration. Ethyl-alcohol has been found to have a greater retardation effect than 1–4 dioxane.
