Physical Properties of Earth-Based Materials Stabilised with Biopolymer Binder

The use of cement-based building materials in the construction sector has become widespread, leading to a rise in carbon footprint and costs. This has created a need for sustainable construction to address the environmental impact. In recent years, researchers have renewed their focus on natural earth-based materials used in earlier eras because of their environmentally friendly and economical properties. However, the low mechanical properties of these materials underline the need for stabilisation. Therefore, to address the environmental impact of synthetic materials, there has been an increased focus on improving the mechanical properties of these materials with materials of biological origin. The aim of this research was to examine the physical properties of a mixture of earth materials with varying concentrations of guar gum (0%, 0.1%, 1%, and 5%). In this study, physical parameters such as unit volume weight, flow table test, air content, and penetration depth in the fresh state, as well as flexural and compressive strength tests in the hardened state, were conducted. The objective of this research is to determine the suitable usage rates of biopolymers and to provide insight into the future use of bio-stabilised earth-based materials.
