HYDRATION-LIMITED, POLYMER-MODIFIED HYDRAULIC CEMENTS

THE RATE OF EVAPORATIVE WATER LOSS FROM THIN SECTIONS OF COMPOSITIONS OF PORTLAND CEMENT MORTAR CONTAINING VARIOUS POLYMERS OF DIFFERENT TYPES AND LEVELS WAS STUDIED. THE POLYMER TYPE AND LEVEL DO NOT AFFECT THE WATER LOSS RATE. MODULI OF ELASTICITY AND RUPTURE WERE DETERMINED FOR VARIOUS POLYMER TYPES, LEVELS, AND HARDENING CONDITIONS, AND FOUND TO DEPEND PRIMARILY UPON THE EXTENT OF THE CEMENT HYDRATION ACHIEVED AND ADHESION LEVEL DEVELOPED. RESULTS OF MICROSCOPIC STUDIES OF THE STRUCTURES OF THE COMPOSITIONS AND FRACTURE SURFACES ARE GIVEN, AND METHODS FOR EVALUATING ADHESION LEVELS IN SUCH COMPOSITIONS ARE DESCRIBED. /AUTHOR/
