In this study, the effects of recycled materials such as fly ash, wood ash, magnesium slag, and cement and polyamide fibers on the strength and stress-strain behaviour of lime concrete have been investigated. Based on the review studies and the tests performed on materials, the optimum mix designs for lime concrete have also been identified. The optimum amount of water and clay for preparing lime concrete samples were considered at 24% and 23%, respectively. Samples with the optimum amount of clay, lime, water, and coarse-grained soil and recycled additives were prepared. The amounts of additives used in different samples were selected as 4% magnesium slag, 4% wood ash, 4% fly ash, 4% cement and 1% polyamide fibers. The amount of lime in the samples was selected in a way that the total percentage of additives and lime was 8%. After curing the samples for 28 days, the uniaxial compressive strength tests were carried out. The results showed that the highest strength was obtained from the lime-fly ash concrete, and the best ductility behaviour was achieved for that concrete made of lime and polyamide fibers.
