USE OF RETARDERS WITH CEMENT TREATED SOILS; FINAL REPORT

AN INVESTIGATION WAS MADE OF SET RETARDING ADMIXTURES FOR POSSIBLE USE AS AN ECONOMICAL METHOD OF ALLOWING LONG DELAYS BETWEEN THE MIXING OF CEMENT, SOIL AND WATER AND REMIXING. A PROCEDURE BASED ON A PENETRATION TEST WAS DEVELOPED. SUGAR-LIME COMBINATION WAS SELECTED AS THE RETARDER. USING X-RAY DIFFRACTION, AN ATTEMPT WAS MADE TO DETERMINE IF ANY KEY COMPOUNDS OF HYDRATION FORMED THAT COULD BE USED AS INDICATORS OF EFFECTIVE RETARDATION. THE RESULTS SHOWED THAT THE SUGAR-LIME RETARDED CEMENT PASTE DID NOT DEVELOP CALCIUM HYDROXIDE REFLECTIONS UNTIL SET OCCURRED, WHICH WAS AT A MUCH LATER TIME THAN IN THE RETARDED SOIL-CEMENT SPECIMENS. IT WAS CONCLUDED THAT THERE WAS NO HARMFUL EFFECT ON THE DURABILITY OF RETARDED SOIL-CEMENT MIXTURES AS MEASURED BY FREEZING AND THAWING TESTS. A FIELD PROJECT WAS CONDUCTED TO DETERMINE THE FEASIBILITY OF USING THE SUGAR-LIME RETARDER IN THE FIELD. IT WAS CONCLUDED THAT THE PROPERTIES OF CEMENT TREATED SOILS WILL NOT BE IMPAIRED IF THE COMPACTION IS DELAYED FOR 6 HOURS, OR IF THE MIXTURE IS REMIXED AND COMPACTED AT 6 HOURS AND IF THE MIXTURE IS COMPACTED IMMEDIATELY AND NOT REMIXED. /AUTHOR/
