PHENOMENON OF AGGREGATION IN THE STABILIZATION OF SOILS WITH CEMENT

THE PHYSICOCHEMICAL CHANGES CAUSED BY THE STABILIZATION OF A BLACK COTTON SOIL AND AN ALLUVIAL CLAY WITH PORTLAND CEMENT ARE DESCRIBED. WITH BOTH SOILS, THE ADDITION OF CEMENT CAUSES AN AGGREGATION OF CLAY FRACTIONS INTO COARSER PARTICLES. THE EXCHANGEABLE BASES OF CLAYS ARE ALSO AFFECTED BY THE ADDITION OF CEMENT. THERE IS AN INCREASE IN THE EXCHANGEABLE CALCIUM, AND THE SODIUM AND POTASSIUM IONS ARE COMPLETELY REPLACED BY CALCIUM IONS GENERALIZED BY THE HYDRATION OF THE CEMENT. THE AMOUNT OF ALKYL INCREASES WITH THE CEMENT CONCENTRATION AND EVEN WITH SMALL AMOUNTS OF CEMENT SOME OF THE FREE LIME LIBERATED REMAINS UNREACTED. IN TIME, HOWEVER, ALKYL DECREASES. THE POSSIBLE MECHANISM OF SOIL-CEMENT REACTIONS IS OUTLINED. /AUTHOR/
