DETERMINATION OF THE CEMENT CONTENT OF HARDENED CONCRETE BY SELECTIVE SOLUTION

THE METHOD OF SELECTIVE SOLUTION BY METHANOLIC MALEIC ACID, DEVELOPED BY TABIKH, ET AL, FOR THE DETERMINATION OF CEMENT CONTENT IN HARDENED CONCRETE, WAS EVALUATED. IT WAS FOUND TO BE RELATIVELY SIMPLE AND INEXPENSIVE, AND IS ACCURATE TO WITHIN PLUS OR MINUS 1 PERCENTAGE POINT CEMENT AT THE 95 PERCENT CONFIDENCE LEVEL WITH THE USE OF CALIBRATION CURVES. SUCH FACTORS AS AGGREGATE AND CEMENT COMPOSITIONS, CURING TIME, AND WATER-CEMENT RATIO WERE INVESTIGATED AS TO THEIR EFFECTS ON THE METHOD. AMONG THESE FACTORS, AGGREGATE COMPOSITION WAS THE ONLY ONE FOUND TO HAVE A SIGNIFICANT EFFECT ON THE ANALYTICAL RESULTS. THE DETERMINATION OF CEMENT CONTENT BY THE MEASUREMENT OF THE SPECIFIC GRAVITY INCREASE IN A METHANOLIC MALEIC ACID SOLUTION WAS ALSO INVESTIGATED, BUT WAS FOUND TO HAVE UNSATISFACTORY PRECISION. /AUTHOR/
