Sustainable construction is an urgent theme in both industrial and developing countries where the construction sector consumes 36% of worldwide energy usage and 40% of the natural resources. Moreover, it causes a hug adverse impact on the environment. One of the major practices to achieve sustainability in construction sector is the use of waste and recycled materials as building materials. The use of waste reduces the consumption of natural resources, energy consumption and carbon emissions. This study is carried out on three types of waste and by-product materials; excavation waste, crushed red brick, and fly ash (FA) which emits from coal-fired thermal plants. The study aims to assess these materials to produce rammed earth as sustainable solution reduces resource consumption, energy consumption, and the environmental pollutants caused by building activities and industrial waste. In order to achieve that, five FA levels 0%, 5%, 10%, 15%, and 20% were mixed with excavation waste of natural soil, and crushed red brick to prepare five rammed earth mixtures. The samples were tested for compressive strength, dry shrinkage, erosion resistance, and microstructure analysis using the scanning electron microscope. The obtained results show that the aforementioned materials can be utilized to produce rammed earth comply with the standard requirements. Also, the observed results indicate that the better properties were measured for mixture prepared using 20% fly ash.
