Olden adobe structures had been commonly built on raw clayey earth hence the technique was exposed to be an eco-green and globally sustainable construction. Nowadays, modern construction materials lack long-lasting stability, affordability, and eco-friendliness. On the other hand, overutilization of earth-based materials led to the depletion of natural resources. So, global construction societies were raised to develop organic construction for an eco-friendly environment. This paper reviewed the recent research on the earthen clay adobe bricks and mortar stabilized with Agro-wastes and how they contended with adaptability and stability standards. The literature study focuses on the ability of the rejuvenated clay adobes rather than the traditional clay adobes of historical times. Agro-waste, non-agro-waste, and some synthetic components were used to enhance the adobe's mechanical, durable, and thermal behavior. This review emphasized altering raw clay and Agro-waste or waste additives by endorsing W/B proportions. From the literature, the scientific interpretations were conferred to attain possible usage of alternate binders and Agro-waste additives with viable W/B ratio. The prime findings of this review were subjected to define modifications of raw clay by adding disposal wastes and alternate binders to resolve the shortage of raw clay resources. Nominal mixing strategies of altered clay bricks are to be prescribed since adobes have no specific standards. The renovations of earthen adobe construction are essential to progress and to satisfy commercial needs as an environmentally sustainable material.
