PROPERTIES OF CEMENT MORTARS MODIFIED BY POLYMER EMULSION

THE AIM OF THESE EXPERIMENTS WAS TO CONTRIBUTE TO THE UNDERSTANDING OF THE MUTUAL INFLUENCE OF POLYMER AND CEMENT DURING THE HARDENING OF THIS COMBINED SYSTEM. POLYVINYLACETATE AS WATER-EMULSION WAS CHOSEN AS REPRESENTATIVE OF POLYMERS FOR ALL EXPERIMENTS. THIS PAPER DEALS WITH THE RESULTS OF THE EXPERIMENTS WITH POLYVINYLACETATE-MODIFIED CEMENT MORTARS, THE EFFECTS OF POLYMER ADMIXTURES ON COMPRESSIVE, TENSILE, AND FLEXURAL STRENGTH, ON MODULUS OF ELASTICITY, THE EFFECT OF RELATIVE HUMIDITY, AND OF POLYMER PLASTICIZER ON SHRINKAGE. THE DEPENDENCE OF STRENGTH ON DIMENSION OF TEST SPECIMENS AND THE BEHAVIOR OF THIS MORTAR IN WATER EXPOSURE AND IN WEATHEROMETER, RAPID-CYCLE EXPOSURE ARE DISCUSSED. CONSIDERATION OF THE RESULTS SUGGESTS FUNDAMENTAL IDEAS ABOUT THE STRUCTURE FORMATION OF POLYMER-CEMENT MIXTURES. /AUTHOR/
