Notes:
Plasticity indexes (PI) of clay bodies including bottom ashes (BA) and various wastes byusing Atterberg limits were measured for the effective recycling of coal bottom ashes from thepower plant. Coal bottom ash (BA)-red clay (RC or simply clay), dredged soil (DS)-BA, coal flyash (FA)-red clay, DS-FA were used as samples for the PI measurement. From the comparison ofclay bodies with BA and DS, PI of DS-BA body was higher than that of BA-red clay body becauseliquid limit (LL) was high and plastic limit (PL) of DS-red clay was low, respectively. Comparingclay bodies with FA and BA, PI of BA-clay body was higher than that of FA-clay body becauseboth LL and PL of BA-clay body were low. When stone ashes and sewage sludge (SS) were addedto BA-clay bodies, PI decreased with increasing both stone ash and sewage sludge contents. It isconcluded that the measurement of plasticity index can be used as an indicator of formingperformance of green bodies with various compositions
