Earth reinforcement is an ancient stabilization method for developing environmentally friendly building materials, which not only attracts the attention of researchers but has been widely used in civil engineering and construction [21, 22].
But to date, studies on the valorization of its fiber as reinforcement in the production of earth bricks for construction are still in progress and this gives an insight on the significant potential to propose to construction engineer’s bio-sourced bricks reinforced with bambusa valugaris fibers.

Machines in diverse fields such as mechanical engineering [7–10], transportation [11–14], and mining [15–18] are constantly being developed to enhance their safety, reliability, and efficiency.
ECRs can be efficiently used as head or balancing ropes in hoisting installations, as belts in conveyor transportation systems, and as stay ropes in industrial or civil structures and buildings.

The thicker and weaker 3ITZ is responsible for the adverse effects of employing recycled aggregate, resulting in inferior engineering and structural properties.
In the converse, the disadvantages comprise majorly the adverse effects on technical or engineering properties.
