Clay Composition of Commercial Clay Deposits.

A laboratory study was made on 55 clay samples to identify the clay mineralogy and the percent of silt and clay particle sizes. X-ray was used to identify the clay minerals. Soil suspensions and settling times were used for the grain size analysis. The results were compared to the commercial use and the atterberg limits. Distinct correlations were found between the clay mineral type and the industrial use for many samples. However, those samples that occur near the boundary of industrial groupings on the plasticity chart were found to contain admixtures of clay minerals. Therefore, identification of the clay mineralogy alone is not sufficient to define the potential industrial use. The atterberg limits are a very necessary test in assessing a clay for exploitation.
