“…As shown in Figure 2, a stepwise procedure is conducted to make the OPS concrete strong, durable, and resistant to chemical attack. A special mix design is considered to make the OPS concrete as these absorb more amount of water as mentioned by Vandanapu and Krishnamurthy [12]. OPS aggregates are soaked in water and dried to room temperature.…”

Oil palm shells (OPS) are mechanical waste that is utilized as coarse aggregates in lightweight concrete. These OPS have shape and strength like conventional aggregates yet the substantial made with these OPS invigorates a limit of 18 MPa. The characteristic strength which must be utilized in structures is seen to be around 25 MPa to 30 MPa. Considering the strength as one of the boundaries for design to be sturdy, the OPS are surface-covered with nanosilane compound. This nanosilane covering goes about as infill on the outside of the aggregates and holds the concrete paste as traditional cement. Operations are permeable in nature; their inner construction has permeable design which makes the aggregates frail. Nanosilane coatings go about as holding between the concrete stage and aggregate stage and hold the substantial solid. In the present examination, mechanical and underlying conduct of nanocovered oil palm shell lightweight concrete is contrasted with that of regular cement. Nanocovered oil palm shell lightweight substantial shows comparative strength as customary cement and decrease in nonsustainable wellspring of energy in oil palm shell lightweight concrete. Supplanting of customary cement with oil palm shell concrete addresses the modern waste which can be utilized for making concrete solid and solid. Morphology and material portrayal of oil palm shell and ordinary aggregates are investigated.

“…The answer to both is the use of lightweight structures. In fact, the main use of lightweight structural concrete is to reduce the load of a concrete structure, which allows a reduction in the size of the structural elements (beam, pillar, and foundation) and a consequent reduction of earthquake forces on the structure [ 45 ].…”

In the last 20 years, there have been a series of seismic events in Italy that have caused serious damage to civil and building structures. This has led to a significant increase in the use of concrete for the reconstruction of new structures and the repair of existing structures damaged by earthquakes. At the same time, the concrete industry is responsible for the most significant environmental damage during the life cycle of the built environment. The environmental disadvantages characterizing the concrete industry are related to the constant growth of the exploitation of natural aggregates. Therefore, it is necessary to use alternative and innovative aggregates that provide good concrete performance and lower environmental impacts. In this study, a very promising route from an environmental point of view is given by the use of artificial aggregates from industrial waste as substitutes for natural aggregates. An innovative low cost and energy saving granulation process has been employed to produce lightweight aggregates using fly ash from the incineration of municipal solid waste and ground granulated blast furnace slag. The final aim of this research is to demonstrate the environmental sustainability of artificial aggregates, through a comparison of three different mixtures.

“…Vandanapu and Krishnamurthy [17] have studied the seismic performance of a six-storied reinforced concrete framed structure using a structural grade of lightweight concrete with a modulus of elasticity of 16 GPa and also normal concrete with a modulus of elasticity of 27 GPa. They reported that the bending moment and shear force of the members were reduced to 15 and 20%, respectively, when lightweight concrete was used instead of normal-weight concrete in the structure.…”

Considering sustainability in all stages of construction engineering is a need to protect environment, preserve natural resources and the earth for our own and future generations. An effective way to mitigate environmental impacts of the construction industry is the use of sustainable materials in construction. Among all types of construction materials, concrete is the most-used material for civil and industrial infrastructures. Therefore, successful production and application of green concrete is vital in the industry. To achieve sustainability in concrete production, there are a lot of efforts of researchers to produce concretes by incorporating wastes and by-product materials as cement and/or aggregate replacement in the concrete mixtures. For the past decades to now researchers are trying to develop sustainable concrete using agricultural solid wastes as the aggregate to produce structural concrete. However, these types of concretes are not practically used in the construction industry. This paper is a brief review on the oil palm shell concrete mixtures and discussed the challenges and barriers of implementing this concrete in the practice.
