UNCERTAINTY IN DETERMINATION OF CEMENT CONTENT AND MIX PROPORTIONS OF HARDENED CONCRETE

THE DETERMINATION OF CEMENT CONTENT AND MIX PROPORTIONS OF HARDENED CONCRETE BY MEANS OF CHEMICAL ANALYSIS INVOLVES UNCERTAINTIES DUE TO THE FOLLOWING FACTORS.: (1) SOLUBLE AGGREGATES, (2) AN UNDETERMINED AMOUNT OF CHEMICALLY FIXED WATER CONTAINED IN THE CEMENT, AND (3) AN UNKNOWN COMPOSITION OF THE CEMENT USED IN THE CONCRETE. VALUES OF CORRECTION OF THE CEMENT CONTENT WHICH TAKE ACCOUNT OF VARIATIONS IN THE ABOVE-MENTIONED FACTORS HAVE BEEN COMPUTED FROM A MASS BALANCE OF THE CONSTITUENT MATERIALS. BY INTERPOLATING BETWEEN THE TABULATED VALUES IT IS POSSIBLE TO ESTIMATE THE MAXIMUM AND MINIMUM VALUES OF CEMENT CONVERT AND MIX PROPORTIONS. /RRL/
