Waste foundry sand. Environmental implication and characterization [PDF]
Geologia USP. Série Científica, 2012 This paper presents the results of analyses using Scanning Electron Microscopy in field samples of waste foundry sand, as well as the results of granulometric, chemical and groundwater analyses. Field data allowed to characterize waste foundry sand and showed that there are elevated concentrations of metals in the groundwater (iron, manganese, boron ...

Waste Foundry Sand in Concrete Production Instead of Natural River Sand: A Review [PDF]
Materials, 2022 The by-product of the foundry industry is waste foundry sand (WFS). The use of WFS in building materials will safeguard the ecosystem and environmental assets while also durable construction. The use of industrial waste in concrete offsets a shortage of environmental sources, solves the waste dumping trouble and provides another method of protecting ...

An investigation of waste foundry sand in asphalt concrete mixtures
Waste Management and Research, 2006 A laboratory study regarding the reuse of waste foundry sand in asphalt concrete production by replacing a certain portion of aggregate with WFS was undertaken. The results showed that replacement of 10% aggregates with waste foundry sand was found to be the most suitable for asphalt concrete mixtures.

Hydromechanical behaviour of a waste foundry sand [PDF]
E3S Web of ConferencesWaste foundry sands are a byproduct of cast-metal processes. There is minimal geotechnical characterisation of these artificial soils in the literature, and as such their potential applications in construction have not been extensively explored. Due to the presence of coal and bentonite, their unsaturated properties, hydraulic behaviour, and mechanical

Research on regeneration methods of animal glue waste sand for foundry [PDF]
Royal Society Open Science, 2018 Sand moulds are used in the casting process. However, after heating, the binder in the sand loses the binding properties, and the most part of the foundry sand has to be discarded from the process. The waste foundry sand after the regeneration can be recycled, and reclamation can reduce the production cost and lower waste emissions.

Recycling of waste foundry sands by chemical washing method [PDF]
China Foundry, 2019 This study aims to remove the metals (inorganic and heavy metals) in waste foundry sand (WFS) via chemical washing method. Washed waste foundry sand (WWFS) samples were obtained by using triptych washing successively with 5 M HCl, 5 M H2SO4 and 5M NaOH solutions.

Waste foundry sand characterization as paving aggregate
Transportes, 2021 Waste Foundry Sands (WFS) are by-products of the steel industry due to the foundry process. The residual material can be used in civil construction as an aggregate because of its mineral origin. This paper aimed to characterize the WFS obtained at two sources, using laboratory tests that are regularly required in highway engineering specifications ...

Evaluation study of hybrid fibre reinforced concrete using waste foundry sand and vermiculite [PDF]
E3S Web of Conferences, 2023 In this work, leftover foundry sand and vermiculite were used as partial replacements for fine and coarse aggregates in hybrid fibre reinforced concrete (HFRC). The study also concentrated on HFRC mix percentage optimization to achieve desired attributes.
