LINSEED OIL BASED COMPOUND USED FOR CURING CONCRETE

A NEW WATER-SOLUBLE LINSEED OIL BASED COMPOUND WAS DEVELOPED THAT SERVES AS A COMBINATION OF A CURING MEDIUM AND A PROTECTIVE COATING FOR PORTLAND CEMENT CONCRETE WORK. PREVIOUSLY THE LINSEED OIL PROTECTIVE COATING WAS APPLIED AFTER 28-30 DAYS CURING TIME. FIELD TESTS USING THE NEW COMPOUND AND STANDARD CURING MEDIA AS CONTROLS WERE CONDUCTED; RESULTS INDICATED THAT THE NEW COMPOUND-TREATED CONCRETE HAD A COMPRESSIVE STRENGTH EQUAL TO OR GREATER THAN CONCRETE IN WHICH THE OTHER CURING MEDIA WAS USED. FULL FIELD USE WAS MADE IN 1969 ON FOUR PROJECTS OF THE INTERSTATE SYSTEM; ALL PAVEMENT CORES TAKEN FOR COMPRESSIVE STRENGTH TESTS WERE ABOVE REQUIREMENTS AND THE PAVEMENT SURFACE SHOWED NO SIGNS OF HAIR CRACKS. APPLICATION IS DONE BY SPRAY MACHINE AS OTHER LIQUID CURE MEDIA; THE RATE IS 150 SQUARE FEET PER GALLON OF DILUTED COMPOUND (60% CONCENTRATE, 40% WATER). THE LINSEED OIL COMPOUND DISCOLORS THE FRESH CONCRETE SURFACE SO THAT VISUAL INSPECTION FOR COMPLETE COVERAGE IS POSSIBLE. ALSO, IT WAS FOUND THAT PAVEMENT CURED WITH THIS NEW COMPOUND RETAINED TRAFFIC MARKING PAINTS LONGER; THE SURFACE DID NOT SPALL OFF AS READILY AS DID PAVEMENT SURFACES CURED WITH OTHER MEDIA.
