N2 - The effect of the addition of cellulose microfibrils, water soluble polymer, nanoclays and carbon nanotubes to the cement paste was studied. The hydration kinetic was determined by means of an adiabatic rise temperature method. The addition of polymer to the cement paste produced the highest delay in the hydration kinetic followed by the addition of organically modified montmorillonites in a polymer solution. Flexion and compression strength were determined. Some admixtures produced an increase of the cement paste's void content. Cellulose produced a change in the rheology and a delay in the hydration kinetic of the cement paste. The use of heat for curing increased the mortar's mechanical properties. Carbon nanotubes also were added to the cement paste in order to study the effect on electric conductivity and hydration kinetic.
