Improving the adobe structures by bio friendly materials

Adobe, a sustainable, inexpensive, and environmentally friendly material, is used in approximately 30% of the world's housing and constitutes 10% of UNESCO's registered heritage sites. However, the long-standing challenge of strengthening clay materials and adobe structures has led to the exploration of various techniques, including the addition of strengthening agents.This research investigates the potential of climate-compatible biopolymers as an alternative to traditional soil stabilizers, aiming to develop an eco-friendlier approach to reinforcing earth and adobe structures. Specifically, we explore novel biological technologies for strengthening clay and adobe, comparing their performance against traditional stabilizers.Our study involves creating various sample combinations using traditional additives like cement, lime, and sand, alongside the bio-friendly material chitosan, at different percentages. These samples undergo laboratory testing to provide a robust and scientific comparison of their properties. Notably, the production of these samples requires minimal energy, suggesting a potentially low embodied energy and reduced greenhouse gas emissions for the final product.Preliminary mechanical tests, including bending and compressive strength analyses, indicate significant improvements in samples incorporating chitosan.
