 This study investigates the development and thermo-mechanical characterization of and fired solid bricks made from clay and timidite sheet wall. The bricks are composed of multiple layers of wall and clay, which are arranged in opposite directions. The wall provides improved thermal and mechanical performance, while the clay provides structural stability. The bricks exhibit increased flexural strength and decreased compressive strength compared to pure clay bricks. Additionally, the bricks have higher thermal conductivity than pure clay bricks due to the presence of the wall. Overall, the bricks offer excellent thermal insulation and mechanical performance, making them suitable for use in sustainable building applications.
