Abstract: Hardening of cement mortars modified with water-soluble polymers comprises both cement hardening by hydration as well as polymer solidification by coagulation and film formation. The paper deals with the effect of the presence of water-soluble polymers on the cement hydration reactions. Retardation of hydration, higher degree of hydration and improved microstructure are observed. Such effects are studied by means of isothermal calorimetry, thermal analysis and SEM-investigation. Polyvinyl alcohol-acetate (PVAA), Methylcellulose (MC) and Hydroxyethylcellulose (HEC) are applied in a 1 % polymer-cement ratio.
