STUDY OF COMPOUNDS IN DUAL ROLE OF CURING AGENT AND PROTECTIVE TREATMENT OF CONCRETE

MATERIALS THAT COULD PERFORM AS A CURING COMPOUND AND ALSO AS A PROTECTIVE AGENT TO THE SURFACE OF PORTLAND CEMENT CONCRETE WERE EVALUATED BY LABORATORY TESTS AND BY FIELD APPLICATIONS. THE MAJOR CONCLUSIONS WERE: (1) ALL LABORATORY SPECIMENS THAT WERE COVERED WITH LINSEED OIL BASE COMPOUNDS APPLIED FOUR HOURS OR LESS AFTER MOLDING TENDED TO HAVE A SURFACE THAT WAS SOMEWHAT SOFTER THAN THE REMAINDER OF THE SPECIMENS. (2) LABORATORY SPECIMENS COVERED WITH CHLORINATED RUBBER COMPOUNDS APPLIED AFTER THE WATER HAD DISAPPEARED FROM THE MORTAR SURFACE GENERALLY PERFORMED BETTER THAN OTHER AGENTS UNDER THE SAME CONDITIONS. (3) ALL COMPOUNDS PERFORMED SATISFACTORILY ON THE FIELD TEST SECTIONS FOR TWO WINTERS. TRAFFIC WEAR APPEARED TO BE THE LIMITING FACTOR FOR THE EFFECTIVE LIFE OF EACH COMPOUND. /FHWA/
