MOISTURE PENETRATION IN CONCRETE WITH SURFACE COATINGS AND OVERLAYS

TESTS WERE MADE ON CONCRETE SPECIMENS COATED WITH FOUR WATER PROOFING MATERIALS TO DETERMINE HOW DEEPLY THE COATINGS PENETRATED INTO THE CONCRETE. ALSO, COATED SURFACES AND OVERLAID SPECIMENS WERE PONDED WITH SALT WATER AND TAP WATER TO DETERMINE THE EFFECTIVENESS OF EACH IN PREVENTING THE PENETRATION OF MOISTURE INTO THE CONCRETE SPECIMENS. FREEZE-THAW TESTS WERE MADE ON ASPHALTIC OVERLAYS TO DETERMINE THE EFFECT OF FREEZE-THAW CYCLING ON THE OVERLAYS AND THE PORTLAND CEMENT CONCRETE BENEATH THE OVERLAYS. SHEAR TESTS WERE MADE TO DETERMINE THE SHEAR STRENGTH OF CONCRETE OVERLAYS BONDED TO CONCRETE TEST BLOCKS. IT WAS FOUND THAT THE DEEPEST PENETRATION OF COATINGS, 0.054 TO 0.062 IN., WAS MADE BY A MIXTURE OF LINSEED OIL AND KEROSENE. NO DAMAGE WAS FOUND UNDER THE ASPHALTIC OVERLAY AFTER 59 FREEZE-THAW CYCLES. SHEAR BOND STRENGTHS RANGED FROM 61 TO 578 PSI WHEN THE CUBE SURFACES WERE TREATED WITH SURFACE COATINGS AND FROM 367 TO 597 PSI WHEN THE SURFACES WITH COATINGS WERE SANDBLASTED BEFORE OVERLAYING. /AUTHOR/
