摘要: Abstract Plant fibers (especially, wheat straw) are available surplus to requirements in sub-tropical regions. Many researchers have studied these for non-structural applications. However, civil engineering structural applications, depth behavior of straw reinforced concrete (WSRC) with steel rebars is not known. For this purpose, WSRC needs be explored detail load bearing structures. This paper presents the contribution plant (i.e. improving and capacity Reinforced beam-lets varying flexure shear rebars, without inclusion straw, experimentally investigated studying altered due fibers. In addition, start practical implications, pavements considered. The study concluded an increase flexural strength (up 7.5%), energy absorption 30.4%), toughness indices 11.1%) along better crack arresting mechanism by incorporation concrete. Also, pavement containing has comparable design likely more durable sustainable structure.
