Abstract
Samples of clays , shales , and argillites from 21 locations were subjected
to preliminary bench- scale tests for bloating properties , and several samples
were tested for ceramic properties . Samples showing favorable bloating properties
were further tested in a pilot - plant - scale rotary kiln . Physical
characteristics and concrete -making properties of the bloated products were
determined . The Decorah shale from one area made a suitable material for a
lightweight aggregate ; however , the limestone layers in the formation must be
eliminated or the resulting activated lime must be controlled by quenching .
