Resumen:
The effect of the addition of cellulose microfibrils, water soluble polymer carbon nanotubes and nanoclays to the cement paste was studied. The hydration kinetic was determined by means of an adiabatic rise temperature method. The polymer produced the highest delay in the hydration kinetic followed by the organically modified montmorillonites plus polymer solution. The properties of flexion and compression were determined. The admixtures produced an increase of the 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 mechanical properties. Carbon nanotubes also were added to the cement paste in order to study the effect on electric conductivity and hydration kinetic.
