“…Despite reaching maximum flexural strength, fibers continued to maintain sample cohesion, enhancing crack resistance. Beskopylny et al [12] focused on enhancing concrete properties using natural sisal fibers, which do not require extensive production processes, making them cost-effective and environmentally friendly. Concrete samples with 0.25%, 0.5%, 0.75%, 1.0%, 1.25%, and 1.5% sisal fiber content were tested at 15 days of age, with a compressive strength of 48 MPa.…”

This paper comprehensively reviews the incorporation of waste materials and fibers into concrete to enhance its mechanical properties and environmental sustainability. Waste materials, including carbon fiber, coconut shell aggregate, fly ash, waste glass, and marble waste, have been found to significantly improve concrete properties. For example, carbon fiber admixtures enhance compressive, flexural, and split tensile strength, while fly ash and waste glass replacements improve overall properties. The inclusion of recycled nylon fiber (RNF) and crushed recycled aggregate (CRA) also enhances concrete's mechanical properties, with RNF increasing tensile strength and CRA reducing density. Furthermore, the use of natural fibers like sisal and jute has shown potential for improving compressive strength, tensile strength, and durability. Incorporating these waste materials and fibers into concrete not only enhances its properties but also contributes to environmental sustainability by reducing waste accumulation. Further research is needed to optimize their use for sustainable concrete production, highlighting the importance of utilizing fibers for environmental conservation.

“…This is a record value that exceeded the values of previous years (419 ppm for 2021 and 417 ppm for 2020) [ 6 ]. Several studies have been devoted to solving a similar problem—the disposal of agricultural, industrial waste, fuel, and energy complex in concrete, but at the same time in concrete based on cement [ 7 , 8 , 9 , 10 , 11 , 12 , 13 , 14 , 15 , 16 , 17 , 18 ]. At the same time, it should be noted that geopolymer concretes are even more promising, environmentally friendly, and economical due to the absence of clinker binders in them and the use of more environmentally friendly cheap components in their composition, which can significantly approach the implementation of the global environmental agenda.…”

The concept of sustainable development provides for the search for environmentally friendly alternatives to traditional materials and technologies that would reduce the amount of CO2 emissions into the atmosphere, do not pollute the environment, and reduce energy costs and the cost of production processes. These technologies include the production of geopolymer concretes. The purpose of the study was a detailed in-depth analytical review of studies of the processes of structure formation and properties of geopolymer concretes in retrospect and the current state of the issue. Geopolymer concrete is a suitable, environmentally friendly and sustainable alternative to concrete based on ordinary Portland cement (OPC) with higher strength and deformation properties due to its more stable and denser aluminosilicate spatial microstructure. The properties and durability of geopolymer concretes depend on the composition of the mixture and the proportions of its components. A review of the mechanisms of structure formation, the main directions for the selection of compositions and processes of polymerization of geopolymer concretes has been made. The technologies of combined selection of the composition of geopolymer concrete, production of nanomodified geopolymer concrete, 3D printing of building structures from geopolymer concrete, and monitoring the state of structures using self-sensitive geopolymer concrete are considered. Geopolymer concrete with the optimal ratio of activator and binder has the best properties. Geopolymer concretes with partial replacement of OPC with aluminosilicate binder have a denser and more compact microstructure due to the formation of a large amount of calcium silicate hydrate, which provides improved strength, durability, less shrinkage, porosity and water absorption. An assessment of the potential reduction in greenhouse gas emissions from the production of geopolymer concrete compared to the production of OPC has been made. The potential of using geopolymer concretes in construction practice is assessed in detail.

“…Comparing the mechanical properties of the composition with organic coarse aggregate, a decrease in strength indicators will inevitably be observed compared to concretes of normal density; however, such a composition acquires properties characteristic of lightweight concretes—lighter weight, and improved soundproof and heat-shielding properties [ 19 , 30 ]. The SC of the walnut shell are much higher than those of the aggregates of light concretes, which makes it possible to use it as a partial replacement for coarse aggregates in concretes of normal density, giving them properties uncharacteristic of such concretes, with minimal losses in strength indicators [ 31 , 32 , 33 , 34 , 35 ].…”

The partial replacement of the mineral components of concrete with natural renewable analogues in full possession of the performance characteristics of the final material, allows not only the concrete-production process to be made more environmentally friendly and inexpensive, but also to solve an important task for the agricultural industry, which is that associated with waste disposal. The scientific novelty of the work is in the obtaining of new concrete compositions by the partial replacement of coarse aggregate with a natural analogue in the form of a walnut shell, which has the maximum ratio of the strength of the composite to its density, as well as in identifying new dependencies of strength and density and their ratio on the amount of replacement of mineral coarse-aggregate walnut shell. The main goal of this article was to analyze the effect of composition factors on characteristics of concrete with partial replacement of large aggregates with walnut shells and to search for the optimal compound that would make it possible to obtain concrete with a minimum decrease in strength characteristics with a maximum decrease in concrete density. Cubes and prism laboratory samples were made from concrete of normal density with the replacement of coarse aggregate by 5, 10, 15, 20, 25 and 30%, by volume. The main mechanical properties, such as density, strength (compressive, tensile, tensile strength in bending) of the concrete samples were studied. The investigation used standard methods and scanning electron microscopy. An increase into strength characteristics up to 3.5%, as well as the maximum ratio of strength to density of concrete, was observed at a walnut-shell dosage of 5%. Effective partial replacement of coarse aggregate with walnut shells leads to a reduction in the consumption of crushed stone by up to 10% and a decrease in the mass of concrete by up to 6%.
