Performance Analysis on the Raw Material of Nantong Silt Sintered Brick

Through the analysis of the chemical and physical properties of the silt in Nantong, which were compared with the clay, the needs of silt raw material for sintered brick were discussed in the paper. The results showed that, the moisture content of the sail in Nantong were lower than that of the clay, the plasticity indexes of silt of Yangtze River in Nantong section concentrated around 12 which was ideal, the chemical constituents of the silt was similar to clay, part of the mineral contents were different. The silt can be used for replacing clay to produce wall materials. It would provide theoretical foundation of materials selection and usage for sludge products companies in Nantong, as well as the reference for the merging recombination and management in the industry.
