AB  - Earth-based construction materials, particularly mud bricks, have been used for thousands of years and continue to play a vital role in the housing sector of developing regions. It is estimated that nearly 30% of the world’s population currently lives in earthen dwellings, highlighting the ongoing relevance of this traditional building material. Mud bricks are inexpensive, environmentally friendly, energy-efficient, and rely on locally available resources, making them a sustainable alternative to conventional construction materials, especially in rural and low-income areas.
