Mud blocks are affordable, eco-friendly, and widely available construction materials. In Ethiopia, many people, especially in rural areas, construct walls by hand-packing mud onto sparsely placed wooden frames using locally sourced soil, straw, and water in unmeasured quantities. This traditional method, though common, often results in weak wall constructions that fail under rain and wind due to poor strength and durability.
This research aims to address these challenges by enhancing the compressive strength of mud blocks made from locally available earthenware clay soil through the addition of cement, lime, and cereal straw ash. By experimenting with different additive ratios, the study seeks to identify the optimal mix for maximum strength. The findings will guide communities on how to produce durable mud blocks and promote their use in wall construction.
The study also aims to inspire the construction industry to adopt these cost-effective and locally available materials for scientific, sustainable building practices. By improving the strength and lifespan of mud walls, this approach could modernize traditional housing systems while reducing dependence on wood and concrete, ultimately saving costs and fostering more resilient homes.
