One of the most successful and economical ways to enhance clay is to treat it with cement and fibers. This study examines the durability, sustainability, strength, and stiffness performance of fiber-reinforced cement and uncemented alluvium clay. Four distinct fiber types of basalt, carbon, polypropylene, and glass and five various fiber quantities varied from 0.1% to 0.5%, were utilized to establish fiber-reinforced specimens, together with three different cement percentages (7, 10, and 13). Unconfined compressive strength (UCS) to determine the strength and peak strain energy, shear wave velocity to determine the stiffness, soaking tests, and cumulative loss of mass to determine the durability of the compacted samples. To identify significant differences between variables influencing the characteristics of the fiber-reinforced clay, a statistical method (ANOVA) was applied. To find the impact of cemented and non-cemented fiber reinforced clay on the environment, embodied energy and CO2 emissions were used. Uncemented fiber-reinforced clay unconfined compressive strength and shear modulus (G0) have been correlated using a cutting-edge regression model. Additionally, this work suggests special power functions based on the innovative porosity-binder index that can forecast composite characteristics. The study also presents an equation that correlates all the qualities, allowing estimation of the necessary property with just one kind of test.
