“…These fibers are readily available, considerably more economical to process and environmentally friendly. Use of sustainable materials in the construction industry has been a key focus of engineers, researchers, and scientists [1][2][3][4][5][6][7][8]. Several advantages of using natural fibers for cement composites have been reported in literature.…”

Fibers obtained from different parts of the oil palm tree (Elaeis guineensis) have been under investigation for possible use in construction. Studies have been carried out investigating the engineering properties and possible applications of these fibers. However, the experimental methods employed and the values of mechanical and physical properties recorded by various authors are inconsistent. It has therefore become necessary to organize information which would be useful in the design of oil palm fiber cement composites and help researchers and engineers make informed decisions in further research and application. This review provides information about fibers from different parts of the oil palm, their properties, enhancement techniques, current and potential application in cement composites.

“…In addition to these statistics of available environmental data, the ever-increasing cost associated with provision of infrastructure through conventional (but non-sustainable) processes (like mining iron ore for steel production for reinforced concrete), pose a continual difficulty for governments of developing countries in providing decent housing for her citizens. Hence there exists need for research into development of alternative natural fibre materials which are cheap, readily available, considerably more economical in production and usage and more environmentally friendly [2][3][4][5][6][7][8][9][10].…”

The use of vegetative fibres in reinforcing concrete is currently attracting research attention because it is void of the high carbon footprint and cost associated with use of conventional reinforcements like steel. One of such vegetable fibres is the ribs of the leaflets of the oil palm tree whose only use has been for making brooms. However, these ribs referred to as Oil Palm Broom Fibres (OPBF) have mechanical characteristics similar to steel and can be incorporated in concrete to improve its mechanical properties. With a specific gravity of 0.84, an average length of 800mm and cross-sectional diameter varying between 0.20mm (at the tail) and 4.00mm (at the head), maximum tensile strength of 900MPa was recorded in the study, hence making the fibres superior to steel in terms of strength-to-weight ratio. Optical microscopy of fibre cross sections reveals randomly dispersed xylem cavities, a densely packed core but lightly packed cortex. This radial and longitudinal density gradient is responsible for the phenomenon whereby towards the cap of the fibres, the fibres are stiffer in bending but reduces in tensile strength. Investigation of mechanical properties of concrete incorporating OPBF as random fibre-reinforcement was carried out. Although the inclusion of OPBF in concrete reduces its compressive strength, the post-yield behaviour shows that energy absorption of the composite is enhanced, making OPBF-concrete a potential material for low-cost seismic construction.

“…Although techniques are evolving, the principle remains unchanged. For about two decades now [1], there has been a technological debate promoting materials that are both ecological [2,3] and renewable [4,5,6]. At present, there are many materials that can be used in this way, particularly in the agricultural sector.…”

The promotion of ecological and renewable materials is gaining more and more interest. Some authors even maintain that the use of plant biomass helps to protect the environment, without giving any supporting values. The aim of this study is firstly to show how much carbon dioxide is saved by not burning sugar cane bagasse (SCB). Secondly, it highlights the structural advantages of using sugarcane bagasse in construction. To do this, we collected the carbon composition of sugarcane bagasse from the literature and evaluated the amount of carbon dioxide emitted during combustion using the carbon-to-carbon dioxide conversion equation. We then formulated an F0 control mortar. Volume fractions of this control mortar are replaced by sugarcane bagasse. For 0%, 3% and 6% rates of sugarcane bagasse, we obtained F0, F3 and F6 respectively. The results of this study show that the use of sugarcane bagasse in the mortar makes it possible to lighten the loads on the structural elements while improving the flexural strength of the mortar for a rate of 3% of sugarcane bagasse. In addition, the combustion equation shows that, in the best-case scenario, one kilogram of burnt sugarcane bagasse releases 1.77 kg of carbon dioxide. Using mortar reinforced with sugarcane bagasse therefore helps to reduce greenhouse gas emissions. These mortars can also be used as infill elements such as joists.
