The history of soil bricks is synonymous with the history of civilization. The early forms of soil bricks’ application date back to 8000 BC with the construction of buildings in Mesopotamia in present-day southern Turkey. Soil brick is a cheap, locally available and recyclable building material. However, its use has been limited due to its low strength, an affinity for water, and its frequent maintenance requirements. Thus, the aim of this study is to develop environmentally friendly fibre reinforced soil bricks with improved physical, durability and mechanical properties. In order to accomplish this, an investigation into the use of low-cost natural fibre chicken feather and sugarcane bagasse as reinforcement for soil brick is carried out. The use of waste materials in the construction industry is generally of interest and useful for engineers and designers looking for sustainable solutions in construction. Based on extensive experimental investigation, constitutive models showing the relationship between soil brick properties were developed. Response Surface Models that fully predict soil brick properties for up to 180 days were developed. Also, normalised design equations for uniaxial compression were proposed. Based on the constitutive models, detailed Finite Element Modelling of fibre reinforced soil bricks was developed. Parametric studies of compressive tests on the parallel-hole hollow soil cubes and bricks were presented. In addition, Finite Element analysis was performed to assess the influence of different parameters on the behaviour of masonry walls made from the developed bricks. The developed soil bricks can be used for affordable and sustainable housing construction across the world, particularly in developing countries.
