The manufacturing process of the reinforced sample with a thickness of 3.5Â cm, including a single-layer array of 1.5-turn helices: (a) The 1.5-turn helical steel particle. (b, c) The planar array of helices mounted on a plastic mesh netting with dimensions \({40}\times {40}\) cm2. (d) Securing the array in its position within the mold. (e) The reinforced concrete composite after the drying process.
