A COMPREHENSIVE METHOD FOR THE CHEMICAL ANALYSIS OF CONCRETE

A METHOD IS DEVELOPED TO GIVE THE AGGREGATE-CEMENT RATIO AND THE WATER-CEMENT RATIO FOR AN UNKNOWN CONCRETE WITH REASONABLE ACCURACY. IT IS BASED UPON THREE MAIN CONSTITUENTS, VIZ. SOLUBLE SILICON DIOXIDE, SOLUBLE CALCIUM OXIDE AND INSOLUBLES, WHILE THE LOSS ON IGNITION AND CARBON DIOXIDE CONTENTS ARE USED FOR CORRECTIVE PURPOSES. THE METHOD REQUIRES NO KNOWLEDGE OF THE MATERIAL USED FOR THE CONCRETE ALTHOUGH SUCH KNOWLEDGE NATURALLY FACILITATES THE ANALYSIS. THE METHOD CONSISTS OF A TOTAL ANALYSIS OF THE CONCRETE, AS SUCH, COMBINED WITH A THERMAL DECOMPOSITION GIVING TWO AGGREGATE FRACTIONS AND ONE CEMENT FRACTION. THESE FRACTONS ARE USED FOR CORRECTING THE ANALYSES OF THE AGGREGATE AND THE CEMENT, I.E. THE AGGREGATE ANALYSIS IS CORRECTED FOR CEMENT PRESENT IN THE AGGREGATE FRACTION AND THE CEMENT ANALYSIS IS CORRECTED FOR AGGREGATE PRESENT IN THE CEMENT FRACTION. ALTHOUGH THIS METHOD IS INTENDED TO BE USED FOR TOTALLY UNKOWN CONCRETES IT MUST BE EMPHASIZED THAT ALL ADDITIONAL DATA ABOUT THE AGGREGATE, CEMENT, ETC. SHOULD BE USED AS FAR AS POSSIBLE. THIS WILL NOT ONLY MAKE THE ANALYSIS EASIER AND FASTER TO PERFORM, BUT IT WILL ALSO MAKE THE RESULTS MORE ACCURATE. /AUTHOR/
