“…As was observed for other stresses, studies have observed a decreasing trend in shear strength with higher SD contents, which can be attributed to the reduction in the voidfilling potential [40] and the decrease in adhesion in the transition zone between particles Figure 9. Flexural strength for different SD replacements [34,40,43,47,48,85,86,98,100,105,107].…”

The escalating demand for natural resources within the construction industry is progressing upward. At the same time, however, there is a great concern regarding the depletion of these resources. This review paper emphasizes the significance of utilizing alternative aggregate materials in concrete. Particularly, it aims to explore replacing natural sand with stone dust. On the one hand, the depletion of primary sources of natural sand worldwide, combined with environmental and ecological concerns, drives the adoption of alternative aggregate materials for sustainable concrete construction. On the other hand, stone dust, a waste from the quarrying industry, offers a cost-effective and practical solution for producing concrete. This article presents a comprehensive literature review of the main trends in utilizing stone dust in recycled aggregates in the past decade and its influence on concrete properties. It addresses critical research questions regarding the physical and chemical properties of stone dust aggregates compared to natural sand; the impact of stone dust on the workability, mechanical, physical, and durability properties of recycled concrete; and the potential reduction of environmental impacts in terms of energy consumption and emissions through the replacement of natural sand with stone dust. Ultimately, this paper proposes future investigative work based on identified research gaps.

“…These quarry by-products, also known as 'quarry wastes', contain considerable amounts of fine particles that exhibit variable compositions of minerals. In general, quarry waste consists of different material types invariably known as "quarry fines", "quarry dust", "stone by-products", "recycled aggregates", "quarry powder wastes", and so forth [1][2][3]. Quarry dust is considered a residue that forms after rock crushing and screening, with particles less than 75 µm, consisting of silt, clay, and non-quartz particles.…”

Quarry waste fines and eggshells are unavoidable wastes which relentlessly contribute to environmental loads and pollution. Although many studies have suggested various methods for recycling, these wastes remain underutilized due to some technical constraints. In addition, no study has yet explored the possibility of combining quarry waste fines (QWF) and eggshell powder (ESP) for tobermorite synthesis. Tobermorite is the main component which primarily provides strength to autoclaved aerated concrete products. With this in mind, this study seeks to evaluate the potential of QWF-ESP mix at 10%, 15%, and 20% amounts of cement, respectively. The XRF, XRD, and TGA–DTA techniques were used to characterize the waste materials, while physical and mechanical property tests and XRD analysis were performed on the autoclaved samples. It was found that QWF contains 53.77% SiO2 and ESP contains 97.8% CaO which are key components for tobermorite synthesis. This study also revealed that the mixture with only 10% cement has the highest compressive strength among the QWF-ESP samples. Furthermore, the formation of tobermorite in the samples was confirmed through XRD analysis. Hence, the hydrothermal curing of QWF-ESP can be further developed to produce functional tobermorite-bearing materials.

“…Recently, Barhmaiah B et al studied the feasibility of using M-sand and quarry dust in rigid pavement construction [8]. They opined that the quarry dust could be substituted for sand in concrete and further studies were required to understand the variation in temperature, fatigue life, skid resistance on the concrete blocks/slabs.…”

All over the world Concrete is widely used as a sturdy and solid material for various uses. According to International usage, it comes in second place after water. River sand, considered expensive because of its scarce availability, is utilized as one of the raw materials for Concrete. Researchers started looking for potential alternatives for river sand and recent studies by them have shown promising results in using Quarry Dust as a possible alternative for sand and for producing high-quality/strength Concrete. The present study attempted to determine the properties of Quarry Dust and its use as an alternative for river sand in Rigid Pavement construction. Various specimens of M30 Grade Concrete were casted and the test results indicate that by replacing fine aggregate with Quarry Dust the Concrete meets the requirements for Rigid Pavement construction. The strength parameters of M30 Grade Concrete in the form of Cubes, Beams and Cylinders were tested at 7, 14 and 28 days. Compressive Strength Test, Flexural Test and Split Tensile Tests were performed on the test specimens and results show that in concrete up to 40% river sand can be replaced with Quarry Dust and it can be used as an alternative for river sand in Rigid Pavement Construction.
