To study Deterioration of Claystone effect to size distribution, The sample that use to test was Claystone sample that corrected from Mae Moh mine.
So, size distribution of Claystone sample will be same as claystone that dumping and compacted in field, that show blue line in the graph.
The sample was accelerate deterioration by wet-dry process.
The sample was saturate in water 24 hr and dried in oven 24 hr is 1 cycle.
The result in graph show increase of deterioration cycle, size distribution of sample was decreased.
If consider at average size distribution of sample and deterioration rate can write the new graph.
