Traditional Portland cement (PC) is the primary cementitious material used in the production of ed concrete owing to its high strength, dry shrinkage, and durability. Additionally, lime and sand are also commonly used as raw materials in traditional ed concrete production.

Concrete is the material most used in the construction industry and its mechanical ... waste materials in the concrete production may contribute to the conservation of natural ... sand, casting ...

Fig. 4 shows particle size distribution of river sand and waste glass sand together with the recommended upper and lower standard limits of grading according to IS 383, the fineness modulus was 2.65 and 2.71 of river sand and waste glass sand respectively, river sand has slightly finer particles compared to glass sand.

With the rapid development of urbanization, the requirement for infrastructure has increased exponentially. At present, cement-based materials (CBMs) are used as the main raw materials for infrastructure construction due to their low cost, wide source of raw materials and superior performance [1], [2].Around 11.5 billion tons of concrete materials is annually …

This industrial waste dumping to the nearest site which spoils the land and atmosphere as well as it also affects aesthetics of urban environment so use of this waste material in concrete is cost ...

Several researchers have investigated the suitability of WFS in concrete production instead of natural river sand in the last few decades to discover a way out of the trouble of WFS in the …

The disposal of high volumes of organic waste is a global issue. Using organic waste instead of sand as an aggregate material for concrete could reduce the strain on waste treatment processes and ...

For M-40 grade concrete, an experimental investigation was carried out on concrete containing waste foundry sand (WFS) in the proportions of 0%, 10%, 20%, 30%, and 40% by weight. For …

The aim of this study is to examine the possibility of using bauxite mining waste as a fine aggregate replacement for concrete production. The quantities of sand replaced with bauxite mining waste ...

Several applications exist for recycled and reused concrete waste with 50% of CDW (Tam, 2008), such as soil stabilisation, water treatment, gas treatment and production construction material (Ho ...

Natural resources are being continuously extracted for the production of concrete which leads to degradation of the ecosystem. This is also a challenge for sustainability to save Nature. This study seeks to identify a suitable replacement material for river sand and stone aggregate for the sustainable utilization of renewable sources. Manufactured sand (M-sand) …

The disposal of high volumes of organic waste is a global issue. Using organic waste instead of sand as an aggregate material for concrete could reduce the strain on waste treatment processes and on the extraction of finite …

Waste foundry sand (WFS) is a by-product of the metal casting process, which constitutes a sustainable solution as a replacement for natural sand (NS) in the production of …

The sustainability of CBM containing waste material becomes an important concern, therefore, it is crucial to consider its economic and environmental impact in order to elevate the sustainability of CBMs [110], [111]. ... This research sheds light on the potential of desert sand in sustainable concrete production, contributing to environmental ...

Many developed countries like Canada, UK, Hong Kong, Brazil permit the use of industrial waste and recycled concrete to produce low-strength non-structural concrete. According to ACI 229R [38], low-strength concrete materials can have a strength as low as 10 MPa. As such, sawdust concrete is suitable as an alternative material for various ...

Concrete is one of the most widely used materials globally with water being the only material that is used in larger quantities (Xuan et al., 2018).The International Energy Agency reported that ∼25 Gt of concrete is used each year globally (WBCSD and IEA, 2009), which is equivalent to > 3.8 t of concrete per person per year (Petek Gursel et al., 2014).

With a composite density of 1.86 g/cm3 compared to concrete's average of 2.4 g/cm3, and a compressive strength exceeding commercial concrete demands of 23.3 MPa to 30.2 MPa, this lightweight ...

Several researchers have investigated the suitability of WFS in concrete production instead of natural river sand in the last few decades to discover a way out of the trouble of WFS in the...

This indicates that concrete waste in powder form has the potential to be used as material for production of artificial aggregate. However, CSW requires separation of coarser particles with finer slurry which requires multistep process of scouring and filtering, sedimentation process, filter press and then again separation into finer material ...

Utilization of waste material for aerated autoclaved concrete production: A preliminary review ... Three volume-replacement rates of sand with each waste type were explored (25, 50, and 75%). ...

Using discarded sand from foundry as a substitution for sand in concrete produces concrete with good properties, boosting its application in buildings. The use of waste from …

Waste foundry sand (WFS) is a by-product of the metal casting process, which constitutes a sustainable solution as a replacement for natural sand (NS) in the production of concrete. This article provides an overview of two types of WFS, along with their physical and chemical properties.

Foundry sand is the raw material required for making metal-casting sand molds, which are frequently recycled during the casting process. Foundry sand loses its quality after repetitive use, making it unsuitable for use in the process of manufacturing products, and later, is subsequently thrown away as waste, i.e., WFS (Ankush et al., 2017).High-quality silica sand …
