Experimental study of the mechanical properties of burnt clay bricks incorporated with plastic and steel waste materials

Abstract

Traditional masonry bricks are made of clay burnt under high temperatures, resulting in high energy consumption, environmental contaminations and decreased natural raw materials. In order to limit nature risks, inorganic materials have been used to make brick. Four types of materials, including fine and coarse plastic, cast iron, and iron swarf, have been used to make bricks. A total number of 64 specimens were made and tested. The tests results were presented in the form of compressive strength, rupture module, water absorption percentage, and initial water absorption ratio. The result showed that using cast iron powder caused the maximum compressive strength amongst all the samples, and was 46% larger than for the reference bricks. On the other hand, the maximum initial water absorption occurred within the first three hours, while the maximum rate was associated to samples with higher coarse plastic contents.

Influence of Firing Temperature on the Mechanical Properties of Bricks

“…Danso [17] observed burnt bricks produced in Ghana, whose physical and mechanical properties were acceptable. Adding powdered cast iron and fine and coarse plastic particles to the clay brick specimens gave various compressive strengths, water absorption, and modulus of rupture [18]. According to Timothy et al [19], the stacking distances of bricks in the field affect the brick quality, as shown by the compressive strength and water absorption properties.…”

Potential Use of Water Treatment Sludge as Partial Replacement for Clay in Eco-Friendly Fired Clay Bricks

“…Employing recycled materials in brick manufacturing can reduce landfill waste and lower the construction industry's carbon footprint. Furthermore, producing bricks from recycled materials can help preserve natural habitats and minimize the environmental impact of resource extraction [6].…”
