OBSERVATIONS ON THE QUANTITY OF CEMENT IN ALREADY SET MORTARS AND CEMENTS

THE PROBLEM, FREQUENT IN LEGAL QUESTIONS, OF VERIFYING THE CEMENT CONTENT IN AN ALREADY SET CONCRETE, IS STUDIED. IT IS POINTED OUT THAT ERRORS OF AS MUCH AS 18 PER CENT ARE POSSIBLE WHEN THE AGGREGATES USED IN THE CONCRETE CONTAIN CONSTITUENTS WHICH FORM PART OF THE CEMENT. STANDARDS (E.G. THE A.S.T.M.C 85-54) BASED ON THE DETERMINATION OF THE SOLUBLE SILICON, ARE ONLY APPLICABLE WHEN THE AGGREGATES CONTAIN NO SILICIOUS ELEMENTS WHICH CAN BECOME PART OF THE CEMENT. POSSIBLE CASES AND THE ERRORS PRODUCED BY SOME CURRENT METHODS OF CALCULATION ARE ANALYZED. POSSIBLE ECONOMIC CONSEQUENCES OF THESE INEXACT ASSESSMENTS ARE DISCUSSED. /LCPC/RRL/
