EVALUATION OF PLASTICIZERS AND AIR-ENTRAINING AGENTS FOR USE IN CEMENT MORTAR AND CONCRETE
A NUMBER OF PROPRIETORY ADMIXTURES, WHICH HAVE HELPED IN DISPERSING CEMENT PARTICLES OR FLOCCULATING THE SAME, HAVE BEEN USED IN CONCRETE CONSTRUCTION TO IMPROVE THEIR QUALITY, STRENGTH AND DURABILITY. FOUR TYPES OF IMPORTED PLASTICIZERS AND FIVE DIFFERENT AIR ENTRAINING AGENTS HAVE BEEN STUDIED WITH A VIEW TO IMPROVE THE WORKABILITY AND STRENGTH OF CEMENT MORTAR AND CONCRETE. EFFICACY OF INDIGENOUSLY MADE AIR ENTRAINING AGENTS WITH RESPECT TO IMPORTED ONES HAS BEEN COMPARED. THE STUDY HAS REVEALED THAT BY INCORPORATION OF PLASTICIZERS IN CEMENT MORTAR AND CONCRETE, THERE WAS A DEFINITE IMPROVEMENT IN STRENGTH. AIR ENTRAINED CONCRETE GENERALLY EXHIBITED LOW STRENGTH BUT BY SUITABLE ADJUSTMENT OF SAND: AGGREGATE RATIO, IT WAS POSSIBLE TO COUNTERACT THE LOSS OF STRENGTH AND OBTAIN HIGH COMPRESSIVE AND FLEXURAL STRENGTHS IN COMPARISON TO PLAIN CONCRETE MIXES. /CRIC/FESR /LCPC/RRL/A/
