The plasticity index of common brick clay is relatively stable.In terms of this type of material, which depends on crushing process reducing particle size to obtain plasticity, its plasticity index is variable during processing.For example, when a certain coal gangue is crushed below 0.9 mm in the laboratory, according to geotechnical test method, the plasticity index is measured as only 7.2%.However, after adding 40% of excessively fired vermiculite (essentially no plasticity),then adding water, aging, and crushing on the roller, vacuum extrusion,plasticity index of the small sample actually reached 10.5%.For example, when other shales were crushed to less 0.9 mm, the plasticity index is measured as 8.4% according to geotechnical test method.However, after adding 40% (by weight) of fly ash,then mixing with water, aging, and crushing,plasticity index of the small sample extruded by the vacuum extruder reached 9.5%.
