FREEZE-THAW AND SKID RESISTANCE PERFORMANCE OF SURFACE COATINGS ON CONCRETE

RESEARCH PERFORMED TO EVALUATE THE PROTECTION AGAINST FREEZE-THAW SCALING OFFERED BY VARIOUS SURFACE COATINGS OF MATERIALS IS REPORTED. THE PHASE COVERING PENETRANTS, TARS, AND ASPHALTS WHICH HAS BEEN COMPLETED IS COVERED IN THIS REPORT; OTHER WORK ON THE PROJECT CONTINUES. LABORATORY FREEZE-THAW TESTS WERE MADE ON 10 IN. SQUARE PLAIN CONCRETE BLOCKS 2 IN. THICK WITH A 5% SALT WATER SOLUTION PONDED ON THE TOP SURFACE. THE SURFACES IN CONTACT WITH THE BRINE WERE TREATED WITH VARIOUS MATERIALS TO PREVENT BRINE FROM ENTERING THE CONCRETE AND DESTROYING IT IN FREEZE-THAW ACTION. SCALING OF THE SURFACE UNDER FREEZE-THAW CYCLING WAS PERIODICALLY INSPECTED AND RATED ACCORDING TO THE EXTENT OF SCALING. PARAMETERS IN THE STUDY WERE TEMPERATURE AND RELATIVE HUMIDITY DURING CURING, NUMBER OF COATS OF SURFACE TREATMENT MATERIAL, SKID RESISTANCE, CRACKS IN THE CONCRETE, AIR-ENTRAINMENT, EXTENT OF SCALING WHEN COATED, AND THE COATING MATERIALS. THE COATINGS FOUND TO PERFORM BEST WERE A MIXTURE OF EQUAL PARTS OF BOILED LINSEED OIL AND KEROSENE, A MIXTURE OF EQUAL PARTS OF TUNG OIL AND KEROSENE, AND HOT BOILED LINSEED OIL. ONE PATENTED PRODUCT SOLD UNDER THE NAME THOMPSON'S WATER SEAL PERFORMED WELL IN SOME TESTS BUT IT WAS NOT AS CONSISTENTLY A GOOD PERFORMER AS THE LINSEED AND TUNG OILS. TAR AND ASPHALT COATINGS WERE PENETRATED BY THE SALT WATER; AND THE CONCRETE SURFACE, HIDDEN BY THE COATINGS, WAS DETERIORATED IN FREEZE-THAW ACTION. THE LINSEED OIL MIXTURE, WHICH HAS PROVED BENEFICIAL IN VARIOUS PARTS OF THE UNITED STATES IN COMBATTING FREEZE-THAW SCALING, IS EASY TO APPLY AND IS POSSIBLY THE LEAST EXPENSIVE OF ANY OF THE MATERIALS TESTED. ITS SKID PERFORMED BEST OF ALL IN EITHER COATED OR UNCOATED CONDITION. NO TREATMENT WAS FOUND WHICH PREVENTED SCALING AT CRACKS IN CRACKED CONCRETE ALTHOUGH THE AIR-ENTRAINED CONCRETE PERFORMED WELL. /AUTHOR/
