ESTIMATION OF CEMENT CONTENT OF STABILIZED CRUSHED ROCK: A METHOD OF ELIMINATING ERRORS DUE TO AGGREGATE REACTION

THE DETERMINATION OF THE CEMENT CONTENT OF CEMENT TREATED CRUSHED ROCK IS COMPLICATED BECAUSE OF THE PRESENCE OF ROCK CONSTITUENTS WHICH REACT WITH THE REAGENTS USUALLY EMPLOYED (MOSTLY ACIDS). IN THE METHOD DESCRIBED HERE, ACETIC ACID BUFFERED TO PH5, WHICH HAS BEEN SHOWN TO REACT WITH CEMENT BUT NOT WITH LOCAL ROCKS, IS SHAKEN WITH A SAMPLE OF TREATED, CRUSHED ROCK AND THE RESULTING TEMPERATURE RISE IS USED TO ESTIMATE THE CEMENT CONTENT.
