摘要:
Two samples clayed materials, LO and NG from central region in Cameroon were characterized for their valorization in the manufacture of refractory bricks and ceramics. In order to assess the technological properties of these clays, cooking tests were carried out on the test specimens at different temperatures. From particle size analysis, clayed materials studied have a spreading particle size and their plasticity index is between 18 and 47. The mineralogical study reveals the presence of Quartz, illite, kaolin, hematite and feldspars. High level of silica content explains the sandy nature of these clays. Linear shrinkage and density increase with temperature while compressive strength decreases with temperature. Analyses performed on the ceramic specimens after firing show that clay materials studied are suitable for the manufacture of refractory bricks.
