THE MEASUREMENT OF THE PH OF SOIL-CEMENT PASTES AS A DIAGNOSTIC TEST FOR THE PRESENCE OF DELETERIOUS SOIL ORGANIC MATTER

PRELIMINARY INVESTIGATIONS HAVE SHOWN THAT THE PH OF A SOIL-CEMENT MIXTURE WAS DEPENDENT ON THE TEMPERATURE, MOISTURE CONTENT, CEMENT CONTENT AND TIME. A RELATIONSHIP EXISTED BETWEEN THE PH OF A SOIL-CEMENT PASTE MEASURED 15 MINUTES AFTER THE ADDITION OF WATER AND THE UNCONFINED COMPRESSIVE STRENGTH OF THE SOIL-CEMENT AT AN AGE OF 7 DAYS. ALL SOIL-CEMENT MIXTURES HAVING PH VALUE BELOW 12.0 HAD STRENGTHS BELOW 250 LB/SQ INCH AND 90% OF THOSE WITH PH VALUES ABOVE 12.0 HAD STRENGTHS ABOVE 250 LB/SQ INCH. MEASUREMENT OF THE PH VALUE OF SOIL-CEMENT IN THE EARLY STAGES OF HYDRATION AFFORDS A SIMPLE AND RAPID DIAGNOSTIC TEST FOR DETECTING THE PRESENCE OF DELETERIOUS ORGANIC MATTER IN THE SOIL. THE APPENDIX GIVES THE PROCEDURE.
