The study aims to improve the thermal resistance of concrete by using natural fibre. In general, in Gulf countries, the solar heat is too high during the summer season, causing indoor heat in buildings. To combat this, air conditioners are used frequently, which is harmful to the environment and human health. Although there are many materials available to prevent heat at present, this study looked at how to effectively reduce heat indoors by using natural materials. This date palm fibre is a natural material that is widely available in the Gulf region, and it can be used to protect people from solar heat. The primary goal of the research is to determine the mechanical properties and thermal conductivity of concrete with various percentage of date palm fibre. The study discovered that when 0.2% date palm fibre is added to the concrete dosage, to have high thermal resistance and it was proved by the experimental study. Date palm fibre is added in concrete at 0% to 3% with a interval of 0.2%. (DPFRC) Date palm fibre reinforced concrete has excellent thermal resistance and compressive strength from test results. It will boost green energy technology in construction industry. [ABSTRACT FROM AUTHOR]

The date palm tree is a very important crop that is grown on a large scale in Gulf countries like Saudi Arabia and the Sultanate of Oman. Date palm stems and leaves come in large quantities as agricultural residues. The stem and leaves of date palm trees, which are common in the Al-Batinah region, might be easily and cheaply used to extract large amounts of fibre. Moreover, they have durability, as well as various strand textures. Using natural fibres made from renewable resources benefits the environment in terms of waste material use and eco-friendly disposability. Due to their availability, widespread use, renewable nature, cost-effectiveness, and eco-friendliness, natural fibre composites have become the focus of research and development. Use of composite materials has grown more common in vehicle, aircraft, marine, and civil structures due to their balanced mechanical qualities. By fortifying the fibres into polymers, properties including compression, impact strength, hardness, and flexural strength of the composites must be ensured. To create fibre/epoxy composites with improved qualities, date palm fibres are more reliable. However, the strength and properties of the fibres may not be the same for the trees grown in different regions. Therefore, in this work, the strength of the composite produced from DPFs of local varieties is tested for the above-specified mechanical properties. The major objective is to find the possibility of using waste date palm tree fibres (DPF) to get a good natural polymer composite which and can be used for different applications. A suitable epoxy has been used as the binder, and the absorbent nature of DPF is controlled by using sodium hydroxide. After treatment, it enhanced the properties of composites. The maximum impact strength and flexural strength of the composite were observed at 21.42 kN/m and 260.41 MN. which proves the reliability of the local DPF for many high-tech applications.
