EFFECT OF LINSEED OIL COATINGS ON RESISTANCE OF CONCRETE TO SCALING

MANY STATE HIGHWAY DEPARTMENTS USE SURFACE COATINGS TO PROTECT CONCRETE PAVEMENTS FROM DISINTEGRATION CAUSED BY DEICING CHEMICALS. THE EFFECT OF LINSEED OIL, ONE OF THESE SURFACE COATINGS, ON THE RESISTANCE OF CONCRETE TO SCALING WAS TESTED IN THE LABORATORY OF THE U. S. BUREAU OF PUBLIC ROADS. FOUR DIFFERENT CONCRETE MIXTURES WERE USED IN THIS TEST' TWO NON-AIR-ENTRAINED CONCRETES WITH SLUMPS OF 2 1/2IN AND 6INS, AND TWO AIR-ENTRAINED CONCRETES ALSO WITH SLUMPS OF 2 1/2 INS AND 6 INS. TEN IDENTICAL TEST SPECIMENS, EACH 16 INS BY 24 INS BY 4 INS SLABS WITH RAISED EDGE AROUND THE TOPE SURFACE, WERE CAST FOR EACH MIX. LEAVING TWO SLABS OF EACH TEN UNTREATED AS CONTROL SPECIMENS, THE REMAINING SLABS WERE TREATED WITH TWO COATS OF APPLICATIONS OF BOILED LINSEED OIL, OR TWO APPLICATIONS OF LINSEED OIL EMULSIONS. EACH SPECIMEN, TREATED WITH CALCIUM CHLORIDE, WAS SUBJECTED TO 105 FREEZE-THAW CYCLES. FOR BOTH THE HIGH AND LOW SLUMP NON-AIR-ENTRAINED CONCRETES, ALL LINSEED OIL TREATMENTS WERE SUCCESSFUL IN PREVENTING OR DELAYING SCALING. FOR THE AIR- ENTRAINED CONCRETES OF HIGH AND LOW SLUMP, THE TWO COAT APPLICATION OF EITHER BOILED OR RAW LINSEED OIL WERE THE MOST BENEFICIAL TREATMENTS. THE SLABS TREATED WITH TWO COATS OF BOILED LINSEED OIL WERE EQUALLY OR MORE RESISTANT TO SCALING THAN THOSE TREATED WITH RAW LINSEED OIL.
