EXPANDED SHALE AS AN ADMIXTURE IN LIME STABILIZATION

THE POZZOLANIC ACTION BETWEEN LIME AND VOLCANIC ASH OR FLYASH HAS LONG BEEN KNOWN. IT IS ALSO KNOWN THAT OTHER MATERIALS WHEN COMBINED WITH LIME WILL PRODUCE A SIMILAR ACTION, BUT THE INVESTIGATION OF THESE OTHER COMBINATIONS HAS BEEN LIMITED. THIS PAPER GIVES THE RESULTS OF THE USE OF DUST FROM EXPANDED SHALE AGGREGATE AS AN ADMIXTURE IN LIME STABILIZATION. THE EFFECT OF EXPANDED SHALE AND THE UNBURNED RAW MATERIAL ON THE COMPRESSIVE STRENGTH OF THE MIXTURES IS GIVEN AS WELL AS A LIMITED AMOUNT OF DATA ON THE VARIATION OF THE QUANTITIES OF THE EXPANDED SHALE DUST. IN GENERAL, THE RESULTS SHOW CONSIDERABLE INCREASE IN THE STRENGTH OF THE LIME STABILIZED MIXTURES FOR TWO DIFFERENT AGGREGATES, ONE AGGREGATE HAVING A HIGH CLAY CONTENT AND THE OTHER BEING A SANDY GRAVEL. /AUTHOR/
