Abstract

At the present work was studied the influence of Red Mud additions in the concentration range of 45-65 % w/w on the physical-mechanical properties of ceramic materials made with extruded clay + red mud mixtures. All ceramics material obtained were thermal treated in temperature range of 750-1050 ºC, with 1 h of dwell time, and their mechanical properties like: Flexural strength (MOR), Water Absorption, Linear shrinkage before and after firing was measure. The crystalline phases of the raw materials and sintered materials were analyzed by X ray Diffraction and the micro structure by Scanning Electron Microscope (SEM). The results pointed out that it is possible to produce heavy clay products like roof tile and clay bricks with physical-mechanics properties higher than the specifications of the Brazilian technical standard (ABNT) for heavy clay products.
