In this second report, we studied the characterization of materials sintered at temperatures from 800 to 1250℃ from the sludge dredged in Tagonoura Bay. Sintered materials changed color from light brown to black with an increase in sintering temperature. It was found that shirinkage, apparent specific gravity and compressive fracture strength of the materials increased suddenly by sintering at above 1100℃. This result suggests that sintering accelerates above this temperature. According to the results of XRD, a complicated composition change in the albite (NaAlSi_3O_8)-anorthite (CaAl_2Si_2O_8) solid solution occurs, and the content of iron oxide (hematite ; Fe_2O_3) increases with an increase in sintering temperature. Base on the characterization results, it certainly is possible to recycle sludge to soil and construction materials.
