ADMIXTURES IN PORTLAND CEMENT CONCRETE

ADMIXTURES CAN BE USED TO ADVANTAGE IN MODERN CONCRETES. THEY ARE USED FOR "CURATIVE" OR "PREVENTIVE" PURPOSES, FOR EXAMPLE, AIR-ENTRAINMENT; THEY ARE USED AS "AIDS", FOR EXAMPLE, ACCELERATION OF HARDENING; AND THEY ARE USED FOR PURELY MONEY-SAVING PURPOSES, FOR EXAMPLE, WATER-REDUCERS. THE FULL LIST OF BENEFITS IS IMPRESSIVE FOR BOTH PRODUCER AND CONSUMER OF CONCRETE. HOWEVER, THESE BENEFITS ARE CONTINGENT ON PROPER USE AND KNOWLEDGE OF SIDE EFFECTS AND OTHER HAZARDS. AN ADMIXTURE CANNOT COMPENSATE FOR INFERIOR MATERIALS OR BAD PRACTICE. IN MOST CASES, THERE ARE ALTERNATIVES WORTH CONSIDERATION ON ECONOMIC AS WELL AS QUALITY COUNTS. /CGRA/RRL/
