Effect of Micro Organic-inorganic Complex on the Hydration of Portland Cement(II) (Mcchanical and rheological properties of PVA-montmorillonite complex cemenrt system)

ABSTRACT

In the course of cement hydration it was found that the addition of polyvinyl alcohol(contracted as PVA. here after) only in the cement paste could more influence on the set-retardation the depression of heat evol-ution rate than that of montmorillonit only or PVA-montmorillonie intercalation complex (PMIC) due to the effective adsorption of PVA on cement particles. The improved mechanical strength by addition of montmorillonite and PMIC was observed remarkably up to 0.05wt% due to the decrease of macro-pores caused by lowed viscosity or the acceleration of hydration reaction.
