MELAMINE RESIN ADMIXTURE EFFECT STRENGTH OF MORTARS

AN ANALYSIS OF VARIANCE WAS USED TO EVALUATE QUANTITATIVELY THE EFFECT OF A NEW TYPE OF MELAMINE RESIN ADMIXTURE, A 20 PERCENT AQUEOUS SOLUTION OF A SODIUM SALT OF A SPECIAL POLYMERIZED PRODUCT OF MELAMINE AND FORMALDEHYDE, ON THE SETTING, WATER-REDUCING EFFECT AND THE COMPRESSIVE AND FLEXURAL STRENGTHS OF MORTARS MADE FROM GROUND CLINKER AND PORTLAND CEMENT. THIS RESIN GREATLY INCREASES THE RETARDING ACTION OF GYPSUM, ACTS AS A POWERFUL WATER- REDUCING AGENT AND, ABOVE ALL, INCREASES THE COMPRESSIVE AND FLEXURAL STRENGTHS BY UP TO 150 PERCENT FOR MORTARS OF GROUND CLINKER AND BY UP TO 65 PERCENT FOR MORTARS OF PORTLAND CEMENT. THE MAXIMUM EFFECT IS OBTAINED WHEN 6 TO 9 PERCENT RESIN IS ADDED, THOUGH LITTLE ADDITIONAL IMPROVEMENT IS ACHIEVED ABOVE 5 PERCENT. /AUTHOR/
