A new approach for studying plaster beam bending based on DISS Algerian (nano-short-bio-fibres)

Construction materials, particularly plaster (gips), are crucial in civil engineering and architecture. Due to their durability, it is essential to use durable materials. A Berber plant, a renewable and persistent plant, has been chosen to improve the mechanical properties of plaster (gips). The PIGGOT rule of homogenization was used to determine the properties of the total set, with plaster as the matrix and DISS (Scrip) as the reinforcement. A high-order mathematical model was established to study the bending of a new bio-beam using local materials, resulting in the birth of the beam. The results show that the deflection of the bio-plaster beam decreases with an increase in the nano-short-fibre fraction of DISS (Scrip). The main objective is to reinforce plaster and reduce flexion by utilizing the effect of short fibres to enhance shear performance. Another goal is to minimize the flexion of plaster beams. Additionally, this approach aims to introduce innovation in the field of construction and civil engineering while promoting the use of biological substitutes in this sector. This study will be conducted analytically through homogenization and analysing the non-local flexure of beams rather than experimentally.
