Compression Behavior of Foundry Sands

Geotechnical and Structural Engineering Congress 2016, 2016
Beneficial use and recycling of industrial byproducts promotes sustainability in roadway construction. An estimated 15 million tons of waste sands are produced from foundry operations (e.g., casting) in the US annually, out of which less than 28% is recycled and the remainder is landfilled.

Flowable Slurry Containing Foundry Sands

Journal of Materials in Civil Engineering, 1997
This research was carried out to evaluate the use of foundry sands on properties of flowable slurry. Two different flowable slurry mixtures were proportioned for strength levels in the 0.34-0.69 MPa (50-100 psi) range, at 28 days, using two different sources of foundry sand and two different sources of ASTM Class F fly ash.

Cement Stabilization of Foundry Sands

Journal of Environmental Engineering, 1988
Foundry sands from bronze and brass foundries are often classified as a hazardous waste due to the presence of lead. Disposal of foundry sands as a hazardous waste can cost over $150 per ton. By mixing foundry sands with cement, a nonhazardous concrete can be formed, thereby greatly reducing the cost of disposal.

Foundry air contaminants from green sand molds

American Industrial Hygiene Association Journal, 1976
The major gases evolved from foundry molds have been determined in the laboratory. The principal gases evolved during pouring and shakeout of castings include hydrogen, carbon monoxide, carbon dioxide, methane and other low molecular weight hydrocarbons with smaller amounts of ammonia, hydrogen cyanide, and sulfur dioxide.

Investigating the effect of the foundry sand and waste foundry sand on the fracture toughness of concrete

Arabian Journal of Geosciences, 2021
The use of recycled or waste materials in the composition of concrete materials is one of the most applicable solutions for compensating for the lack of initial sources. The effect of waste materials on the mechanical properties of concrete should be assessed before utilizing them in mix design of practical projects such as dam construction and ...

Comparsion of Foundry Properties of Traditional Foundry Sand and Microspheres

Applied Mechanics and Materials, 2012
A case study of the comparison of the properties of conventional foundry sand and light weight cenosphere/microsphere particles has been undertaken. This analysis was initiated by the preparation of their respective specimens, followed by the actual testing of these samples.

Bridging additive manufacturing and sand casting: Utilizing foundry sand

Additive Manufacturing, 2019
Abstract Although additive manufacturing technology is available for the direct fabrication of metal parts, the process is still in a juvenile state compared to older metal fabrication methods such as sand casting. Therefore, limited standards are available stipulating the use of additively-manufactured parts in critical service conditions such as ...

Interaction of Foundry Sands with Geosynthetics

Journal of Geotechnical and Geoenvironmental Engineering, 2001
Excess foundry sands from gray-iron casting are a mixture of sand, bentonite, and additives that can have properties desirable for structural fills and hydraulic barriers, depending on their bentonite content. To facilitate beneficial reuse of foundry sands, typical strength parameters need to be available so that designers can make comparisons with ...
