Potentials of Constructing Sustainable Rammed Earth Buildings in Hot-Arid Regions: Structural and Environmental Challenges

Abstract

The continuous increasing in the price of cement is one of the major challenges facing the construction industry. Moreover, concrete mixtures are main sources of CO2 emissions. On the other hand, rammed earth material could be a good alternative to reduce costs and amounts of emissions. In addition, it is appropriate to be used in hot-arid regions due to its thermal mass properties. Yet, such a material has limitations in terms of durability and strength. This research aims firstly to test the suitability of rammed earth as urban modern construction material, through examining characteristics and specifications of soil, sand, and other stabilizers to improve the resistance to frost attack and avoid deterioration. Secondly, to explore the efficiency in terms of indoor environmental conditions. The research was implemented by constructing an experimental building within a university campus in Jordan, to conclude the best solutions in terms of environmental and structural challenges.
