“…By-products that are obtained in other industrial areas during the production process could be used as alternatives to natural materials. Using such materials provides not only benefits to nature but also economic benefits [ 16 , 17 , 18 ]. Many researchers are looking for alternatives to cement, and the main ones being tested are fly ash, ground granulated blast furnace slag, silicon dust, and rice husks, and these are materials that are obtained from other industrial areas as by-products [ 19 , 20 , 21 , 22 , 23 ].…”

The Influence of Concrete Sludge from Residual Concrete on Fresh and Hardened Cement Paste Properties

In the concrete manufacturing industry, a large amount of waste is generated. Such waste can be utilised in the production of more sustainable products with a low carbon footprint. In this study, concrete sludge, a difficult-to-utilise waste that is obtained from residual concrete by washing a concrete truck, was investigated. During washing, aggregates from the concrete mixture are separated, and the remaining insoluble fine particles combine with water to form concrete sludge. Dried and wet concrete sludge were used in the tests. Samples with different compositions were produced with dried and wet concrete sludge, cement, superplasticiser, and tap water. Seven cement pastes with different compositions were made by partially replacing cement with dried concrete sludge (0%, 5%, 10%, 15%, 20%, 25%, and 30%). In compositions with wet concrete sludge, cement was replaced by the same amounts as in the case of dried concrete sludge. The slump, setting time, and their changes with different amounts of concrete sludge were determined for fresh cement pastes. It was found that with different forms of concrete sludge, the technological properties of the mixtures change, and the setting time decreases. The density and compressive and flexural strength results were confirmed by SEM and XRD tests. The research results show that dry concrete sludge causes the deterioration of the mechanical properties of cement stone, while wet concrete sludge improves the mechanical properties of cement stone. However, it was found that replacing 5% cement with dry concrete sludge does not significantly affect the properties of hardened cement stone. In mixes with wet concrete sludge, the recommended amount of replaced cement is 10%, because the technological properties of the mixture are strongly influenced by larger amounts.

“…The qualities of concrete, such as its workability, strength, and durability, are improved when GGBFS, a byproduct of the iron industry, is added. This substance is produced when iron ore, limestone, and coke are heated to roughly 1500 degrees Celsius [7]. GGBFS does not directly come into being.…”

“…In the majority of cementitious materials, these minerals are present. Ground granulated blast furnace slag cement is further dried, and the particles are ground in a spinning ball mill to create a fine powder [7]. Blast furnace slag is a byproduct generated during the iron production process in a blast furnace.…”

To overcome the environmental impact of cement production in concrete, the construction industry is adopting eco-friendly approaches, such as incorporating alternative and recycled materials and minimizing carbon emissions in concrete production. One such material that has gained prominence is ground granulated blast furnace slag (GGBFS). This study focuses on investigating the compressive strength of concrete at 28 days of age by examining the influences of several factors, such as temperature, water-to-binder ratio (w/b), GGBFS-to-binder ratio (GGBFS/b), fine aggregate, coarse aggregate, and superplasticizer. A statistical modeling approach was employed to comprehensively analyze these parameters and assess their impact on compressive strength. To accomplish this, the study collected and analyzed data from the literature, resulting in a dataset of 210 observations. The dataset was divided into training and testing groups, and statistical analyses were performed to assess the relationships between the input parameters and compressive strength. The correlation analysis revealed insignificant relationships between the input parameters and compressive strength, indicating that multiple factors affect strength. Different models were employed to predict compressive strength, such as linear regression, nonlinear regression, quadratic, full quadratic models, and artificial neural networks (ANN). The findings of this study contribute to a better understanding of the factors that influence the compressive strength of concrete containing GGBFS. The results underscore the importance of considering multiple parameters to predict strength accurately.

“…Even improper rock waste disposal causes the diversion of rivers into farming areas, which leads to the flooding of agricultural lands [2]. The environmental problems due to quarrying include noise, vibration, and dust pollution, soil erosion, diversion of natural drainage systems, destruction of vegetation, and animal habitats [3] On the other hand, urbanisation and industrialization have resulted in the generation of a huge quantity of industrial waste worldwide. This in turn also causes serious problems relating to environmental pollution.…”

The stone quarrying activities to meet the demand for infrastructure development, which in turn impacts on the soil and water resources, affect the hydro-geological and hydrological regimes. Due to the increase in urbanisation and industrialization, a large quantity of industrial waste is produced in developing as well as developed countries, and the unscientific disposal of this industrial waste is creating huge environmental problems. In this study, an attempt is made to incorporate both the problems and to find an alternative for natural aggregates with industrial by-products fly ash and GGBS for manufacturing artificial aggregates by adopting the geo-polymerization technique. The characteristic strength, flexural strength, and split tensile strength of geopolymer aggregate (GPA) concrete for varying percentage replacements, such as 25%, 50%, 75%, and 100% for natural coarse aggregates, have been studied and compared with normal concrete. Based on the test results, geopolymer aggregates could be considered as an alternate source for natural aggregates. The 28-day compressive test results showed that for 75% and 100% replacement, GPA3 concrete has been conducted with XRD analysis and SEM analysis on the microstructure of geopolymer aggregates manufactured with varying mix ratios of source materials and curing periods of X-Ray diffractograms and patterns. exhibit the formation of N-A-S-H and C-A-S-H compounds, which indicates the geopolymer formed has similar chemical compositions as natural rocks.
