Formulation and Physico-Mechanical Characterization of Bricks Composed of Recycled Thermoplastics and Toukra Soil

Abstract

The recovery of thermoplastics has a major impact on our cities, both in terms of the environmental impact of waste disposal and the economic impact of its use in construction materials. The aim of this study is to manufacture bricks from recycled thermoplastics, more specifically low-density polyethylene (LDPE) packaging from households and landfill sites in the 9th arrondissement. The technological evolution that humanity has undergone in recent years has made a wide variety of building materials available, and the use of earth as a material will make use of certain secondary products known as additives. These additions may be of mineral, animal or vegetable origin, and also of low purchasing power, but create a very strong bond once they are combined. The main aim of the present work is to contribute to the characterization of bricks produced from thermoplastics and a soil sample taken from the bank of the Chari at Toukra in the 9th arrondissement of the capital, which are resistant to natural hazards such as bad weather and flooding, which always cause enormous losses with each passing season. The results of the various tests carried out show that the material can help to overcome not only the lack of mechanical strength, but also the impermeability that is the cause of the deterioration and ruin of the building in clay without any addition modifying its properties.
