INVESTIGATION OF A REACTION INVOLVING NONDOLOMITIC LIMESTONE AGGREGATE IN CONCRETE

A LABORATORY INVESTIGATION WAS MADE OF A CHEMICAL REACTION OBSERVED AS RIMS ON NONDOLOMITIC LIMESTONE COARSE AGGREGATE PARTICLES IN FIELD CONCRETE. THE RIMS WERE CHARACTERIZED BY A COLOR VARIATION AND AN INCREASED SOLUBILITY IN ACID. SEVENTEEN LIMESTONES FROM 11 SOURCES WERE USED. THE REACTION WAS DEVELOPED IN THREE OF THE ROCKS IN LABORATORY TEST SPECIMENS, X-RAY DIFFRACTION ANALYSIS LED TO A TENTATIVE EXPLANATION. IT WAS CONCLUDED THAT THIS REACTION COULD OCCUR WITH ALL CARBONATE ROCKS IN CONCRETE AND COULD CONTRIBUTE TO AGGREGATE-PASTE BOND. /AUTHOR/
