Housing is one of the basic needs for human after food and clothing. Unfortunately, deficiency of decent housing is a constant problem in many parts of developing countries, like Ethiopia, where also the population growth is disproportional to shelter delivery. Apart from deficiency, many of the houses are of poor quality which have short life span and unhealthy to live in.
Adequate shelter is one of the most important basic human needs. As per the data from Central Statistical Agency of Ethiopia, the projected data in 2016 is 73.9 million is living in rural area of Ethiopia and when we consider the housing condition in this rural area, 65% of the house are made from wood and mud.
Due to limited means within developing countries, it is necessary to seek ways to reduce construction costs, especially for low-income housing, as well as adopting easy and effective solutions for their repair and maintenance.
Compressed Stabilized Earth Blocks (CSEB) are construction blocks made from a mixture of soil and a stabilizing agent compressed by different types of manual or motor-driven press machines. The blocks are then left in the sun to cure (no firewood needed! natural ventilation) and water is sprinkled to aid curing.
Compressed Stabilized Earth Blocks (CSEB) offer a number of advantages which includes increased utilization of local material and makes quality housing available to more people, and generates local economy rather than spending for import materials. Other advantages are faster and easier construction method, good strength, less carbon emission, and cause no environmental pollution and negligible energy consumption during the whole life cycle.
