Sustainable Eco-Friendly Building Material – A Review Towards Compressed Stabilized Earth Blocks and Fire Burnt Clay Bricks

The aim of the current research article is to provide a comprehensive review and discuss and conclude on two types of earth blocks i.e., stabilized compressed earth blocks and fire-burnt clay bricks. A direct correlation exists between the number of greenhouse gases emitted and the amount of coal used to manufacture the fire-burnt clay bricks. To address this issue, new construction materials have been developed. Compressed Stabilized Earth Blocks (CSEBs) is an enhanced earth-based masonry material as it is not burnt. CSEBs are manufactured by compressing the soil under pressure. Coal and other burning fuels are not used at any point in the manufacturing process of CSEBs. Environment-friendly and energy-efficient construction materials that encourage the sustainable development have grown significantly in the recent years, as the public have become highly conscious. Since the building materials are produced in local communities, the local resources are efficiently used, transportation costs get reduced and high-quality housing is made available to a large spectrum of people. Less time-consuming construction techniques and low labour demand results in increased strength, insulation and thermal characteristics, lower carbon emissions and embodied energy during the life cycle of the materials and exceptionally low levels of trash that can be easily disposed of. When locally-produced materials are used for building purposes, it creates jobs and is more eco-friendly, during the times of crisis. CSEB and conventional bricks require different amounts of energy and release significantly different amounts of carbon dioxide throughout the production process. A review of the construction process that utilizes clay bricks and CSEBs has been conducted using the data and reports from numerous research papers and organizations. According to this review, the Compressed Stabilized Earth Blocks outperform the fire-burnt clay bricks in terms of advantages. When it comes to creating new environment-friendly construction materials, the CSEBs remain a viable option.
