QUANTITATIVE DETERMINATION OF CEMENT IN SOIL-CEMENT BY MEANS OF COMPLEXOMETRIC TITRATION OF CALCIUM AND MAGNESIUM

A METHOD IS PROPOSED FOR THE QUANTITATIVE ANALYSIS OF CEMENT IN SOIL-CEMENT. BASICALLY, THIS METHOD IS A COMPLEXOMETRIC TITRATION OF MAGNESIUM AND CALCIUM CONTAINED IN THE SOIL-CEMENT, IN THE SOIL AND IN THE CEMENT. IT USES 'COMPLEXON III' AS COMPLEXING AGENT AND 'ERIOCHROME BLACK T' AS COLOR INDICATOR AND IS INTENDED TO REPLACE THE CLASSICAL OXALATE METHOD. THE TECHNIQUE WAS APPLIED TO A SAND WITH A LOW CLAY CONTENT AND A LIMESTONE-RICH SILT, WHICH WERE STABILIZED WITH CEMENT QUANTITIES VARYING BETWEEN 5 AND 15%. A STATISTICAL STUDY OF THE SCATTERING OF THE RELATIVE ERROR ON THE TITRATION ALLOWS THAT, FOR THE TESTED SOIL-CEMENT SAMPLES, THE RELATIVE ERROR NEVER EXCEEDS PLUS OR MINUS 3% (WITH 99.8 CHANCES TO 100), I.E., PLUS OR MINUS 0.3% IN ABSOLUTE VALUE FOR A 10% CEMENT MIXTURE.
