Recycling of waste foundry sands

Science of The Total Environment, 1992
Abstract Waste foundry sands are industrial wastes of important quantity. Because of the partially very high contamination of these sands with polyaromatic hydrocarbons (PAH), some of them potent carcinogens, dumping of these sand in landfills without appropriate safety measures, or use in road and landscape construction is very problematic.

Microtox™ characterization of foundry sand residuals

Waste Management, 1998
Abstract Although foundry residuals, consisting mostly of waste sands, represent a potentially attractive, high-volume resource for beneficial reuse applications (e.g. highway embankment construction), prospective end users are understandably concerned about unforeseen liabilities stemming from the use of these residuals.

Utilization of Used Foundry Sand in Concrete

Journal of Materials in Civil Engineering, 1994
This research was conducted to investigate the performance of fresh and hardened concrete containing discarded foundry sands in place of fine aggregate. A control concrete mix was proportioned to achieve a 28‐day compressive strength of 38 MPa (5,500 psi).

Titanium Casting with Sand Foundry Techniques

Journal of Vacuum Science and Technology, 1971
The ability to produce a east titanium configuration has a history of approximately 10 years. It is presently being done in the United States by six companies. Casting of titanium is no simple task when one considers the thousands of foundries in existence producing cast parts from other metals.

Capillarity of concrete incorporating waste foundry sand

Construction and Building Materials, 2013
Abstract Currently, most of the waste foundry sand (WFS) generated in the UK and many parts of the world are sent to landfill. The rising cost of land-filling and the associated environmental problems have prompted the metal casting industry into reusing the WFS.

Waste foundry sand and its leachate characteristics

Resources, Conservation and Recycling, 2010
Abstract Solid waste management has become one of the global environmental issues, as there is continuous increase in industrial by-products and waste materials. Due to lack of land filling space and its ever increasing cost, utilization of waste material and by-products has become an attractive alternative to disposal.

[Environmental toxicity of waste foundry sand].

Huan jing ke xue= Huanjing kexue, 2014
The metal leaching characteristics and volatile organic compounds (VOCs) of five different types of waste foundry sands were analyzed with the toxicity characteristic leaching procedure (TCLP) and head space-gas chromatography (HS-GC). Microtox and soil dehydrogenase activity (DHA) tests were then used to evaluate the bio-effects of these waste sands ...

Mechanical Properties of Concrete Containing Foundry Sand

"SP-200: Fifth CANMET/ACI Conference on Recent Advances in Concrete Technology-Proceeding, Fifth International Conference", 2001
The properties of concrete containing foundry sand as a partial replacement of fine aggregate were investigated. Three types of sand used in foundries were considered, the white fine sand without the addition of clay and coal, the foundry sand before casting (blended), and the foundry sand after casting (spent).

Maintenance Practice in a Sand Casting Foundry

2016
The chapter gives an in-depth review of challenges as well as strengths and weaknesses that characterize maintenance practices in a sand casting manufacturing company. The study was done for a ferrous foundry which was producing mainly grey and white iron.

Potential Reuse of Spent Foundry Sand

2008
The foundry mould mixture is a combination of sand, binders, water, and additives. Sand particles as basic components make up 70-90% of the total mould mixture material. The production of castings generates approximately 2.5 t of spent foundry sand per tonne of steel cast, representing roughly 90% of solid foundry waste. Foundry sand can be regenerated
