A STUDY OF FACTORS AFFECTING ABRASION RESISTANCE OF CONCRETE SURFACES

A LABORATORY RESEARCH PROGRAM ON ABRASION RESISTANCE OF CONCRETE WHICH INCLUDES THE DEVELOPMENT OF AN IMPACT TYPE TEST METHOD TO MEASURE THIS RESISTANCE OF CORE SPECIMENS, IS DESCRIBED. VARIABLES INCLUDED IN THIS STUDY WERE SLUMP, FINISHING, CURING, SURFACE TREATMENTS /INCLUDING LINSEED OIL AND MONOMOLECULAR FILM/, AND THE USE OF ADMIXTURES. SAND WITH A LOW MORTAR STRENGTH WAS SUBSTITUTED FOR THE LABORATORY STOCK SAND IN TWO TESTS. IN ADDITION TO THE ABRASION TESTS ON CONCRETE CORES, HARDENED CONCRETE SPECIMENS WERE EXAMINED FOR AIR CONTENT AND VOID DISTRIBUTION BY THE LINEAR TRAVERSE METHOD. RESULTS OF THESE TESTS AGREE WITH THE FINDINGS OF OTHER INVESTIGATORS THAT SLUMP, CURING, AND TIME OF FINISHING ARE THE MOST IMPORTANT FACTORS AFFECTING THE ABRASION RESISTANCE OF CONCRETE SURFACES. A TWO-COAT SURFACE TREATMENT OF LINSEED OIL, APPLIED WHEN THE CONCRETE HAD PARTIALLY DRIED, WAS FOUND TO INCREASE ABRASION RESISTANCE APPRECIABLY REGARDLESS OF OTHER VARIABLES. A BRIEF SUMMARY OF REPORTS BY OTHERS ON THE CAUSES AND PREVENTION OF CONCRETE WEARING DETERIORATION IS ALSO PRESENTED. /BPR/
