“…Four types of agricultural waste present in India were selected: vermiculite, pistachio shells, sugarcane bagasse, and coconut husks, as shown in Figure 1. The vermiculite, coconut husks, and pistachio shells were not processed, whereas the sugarcane bagasse was crushed into 20 mm × 20 mm pieces using a mortar and pestle (Onochie and Balkis, 2021).…”

Agricultural waste can be used in cement block production for a number of reasons, including its environmental, economic, and labor benefits. This study examines the mechanical, durability, and cost-effectiveness characteristics of cement blocks. A cement block made from agriculture waste promotes sustainable construction practices, since waste agriculture is often dumped in landfills and regarded as a waste material. Carbon dioxide (CO2) emissions produced by the construction sector, either from the firing of clay bricks or from the production of cement, contribute significantly to global warming. In many developing countries, air pollution from agricultural activities is primarily accounted for the emissions from agricultural machinery and openly burning agro-waste. Farming is one of the leading causes of water and soil pollution. Hence, adopting agricultural waste into cement production would significantly reduce the environmental impact of concrete structures. The goal of this research is to determine whether agricultural waste products, such as vermiculite, pistachio shells, sugarcane bagasse, and coconut husks, can be used to substitute sand in concrete blocks. The water absorption capacity of waste materials, density, flexural strength, fire resistance, and compressive strength of waste materials as admixtures in concrete were evaluated using experimental tests. In most cases, the concrete blocks made from agricultural waste were strong enough to satisfy ASTM standards. The specimens containing coconut husks and pistachio shells, among others, were found to be fairly strong and durable, even when isolating them from water.

“…The target of manufacturing composite sustainable materials such as fiber reinforced concrete (FRC) fabricated from recycled materials is to enhance the tensile resistance, ductility and electro-thermal of the concrete mixtures. Four principal kinds of fibers are produced to prepare FRC such as: glass fibers (GF), steel fibers (SF), natural fibers and artificial fibers [7] & [10]. Moreover, plastic fibers are portion of artificial fibers, it could be observed in various formulations like (PP), (PS), (PET), (PVA), (PVC), (LDPE), and (HDPE), or hybrid fibers (a composite of two fibers).…”

“…Environmental goodness inside buildings is a substantial health agent and hence, it is essential to discover environmental materials for the building processes [8]. The aim of producing environmental materials is related to improving materials management, reducing waste, and gaining materials with appropriate physical and mechanical features [9] & [10]. Wastes of plastic could be utilized in many civil engineering applications like; Recycling plastic-waste and as an alternative to aggregates in specific proportions in concrete, attributed to its economic and environmental advantages [11], [12], [13], and [14].…”

Among possible solutions for a cleaner environment is reduction of using non-biodegradable materials to reduce the waste. Solid plastic waste is considered the most important kind of waste in the world, due to its non-decadence and its low organic decomposability. Therefore, it was advised to use this waste as reinforcing materials for concrete units, as it was used as a substitute for moraine in certain proportions and also as reinforcing fibers for concrete. This paper is a review of research investigations that focused on and highlighted the improvement of concrete by recycling waste-plastic food-package and using them as reinforcing fibers for concrete specimens. The impact of plastic waste fibers (PWFs) on workability, compressibility resistance, tensibility resistance, bending resistance, and elastic modulus are demonstrated. It has been noted that the fresh characteristics of concrete decline when mixing plastic fibers with concrete mixtures, while hardened characteristics could be improved by utilizing specific proportion of these fibers

“…It was noticed that the use of untreated natural fibres decomposes with time when exposed to atmospheric agents and in the case of cement stabilized RE, it degrades because of a highly alkaline environment. This problem may be overcome by the use of synthetic fibres like polypropylene fibres which provide very good resistance to fatigue, wear resistance, alkali resistance, and also provide good heat insulation (Onochie and Balkis 2021).…”

Rammed earth (RE) is a brittle material that can undergo sudden catastrophic failures under ultimate stress. Such sudden catastrophic failures can be avoided in RE structures with the addition of randomly oriented polypropylene fibres where crack propagation can be inhibited.Further, the strength of RE can be enhanced by the addition of nanomaterials, which make RE denser because of their high specific surface area. This research deals with studies on the effect of polypropylene fibre and nanosilica on the behaviour of cement stabilized rammed earth (CRE) under compression and flexure. The effect of fibre volume fraction and nanosilica content on the strength and stress-strain characteristics has been evaluated. Three polypropylene fibre volume fractions (0.2%, 0.3% and 0.4%) and five nanosilica contents (0.2%, 0.4%, 0.6%, 0.8% and 1%) were considered in this investigation. The compressive strength of fibre reinforced CRE increased by 30% for 0.3% of polypropylene fibre content and by 41% for 0.6% of nanosilica content when compared to CRE. The strain at peak stress has significantly increased with the addition of fibres indicating improved ductility and postpeak response of the material. The microscopic analysis showed that the addition of nanosilica has contributed to a denser packing of soil particles and hence, might have increased the compressive strength.
