REACTIVITY OF FOUR TYPES OF FLY ASH WITH LIME

THE VARIABLES OF FLYASH THAT AFFECT THE POZZOLANIC REACTION BETWEEN LIME AND FLYASH WERE STUDIED BY MEANS OF UNCONFINED COMPRESSIVE STRENGTH. THE SAMPLES USED IN THIS STUDY WERE MOLDED FROM VARIOUS MIXTURES OF LIME, FOUR TYPES OF FLYASH AND WATER. ALL SPECIMENS WERE MOIST CURED FOR A SPECIFIC PERIOD PRIOR TO TESTING. THE POZZOLANIC ACTIVITY OF FLYASH WAS FOUND TO BE DEPENDENT UPON ITS CARBON CONTENT AND ITS DEGREE OF FINENESS. THE RATE OF THE POZZOLANIC REACTION WAS CONSIDERABLY INFLUENCED BY THE CONDITIONS OF TEMPERATURE AND HUMIDITY UNDER WHICH THE SAMPLES WERE CURED. THE STUDY ALSO REVEALED THAT THE UNCONFINED COMPRESSIVE STRENGTH INCREASES WITH INCREASED LIME CONTENTS. /AUTHOR/
