09-03-2010· In this study, the potential re-use of waste foundry sand in high-strength concrete production was investigated. The natural fine sand is replaced with waste foundry sand (0%, 5%, 10%, and 15%). The findings from a series of test program has shown reduction in compressive and tensile strengths, and the elasticity modulus which is directly related to waste foundry inclusion in concrete.
04-09-2020· Past studies have shown that both slag and spent foundry sand can be used in concrete production as aggregate or cement filler and in most cases the addition of this waste product improves the properties of the concrete [1,2,5]. These efforts have attributed to the percent foundry waste recycled annually, however; the impact is still low.
15-12-2017· Waste foundry sand, a by-product of ferrous and non ferrous metal casting industries is one such promising material which can be used as an alternative to natural sand in concrete. In last few decades, several studies have been conducted to investigate the effect of addition of waste foundry sand as partial and complete replacement of regular sand in concrete.
A control concrete mix was proportioned to achieve a 28‐day compressive strength of 38 MPa (5,500 psi). Other concrete mixes were proportioned to replace 25% and 35% by weight of regular concrete sand with clean/new foundry sand and used foundry sand.
Use of foundry sand in various engg. applications can solve the problem of disposal of foundry sand and other purposes. Foundry sand consists primarily of silica sand, coated with a thin film of burnt carbon, residual binder (bentonite, sea coal, resins) and dust. Foundry sand can be used in concrete to
concrete using waste foundry sand and recycled aggregate concrete. 2. EXPERIMENTAL PROCEDURES: 2.1 Materials The Ordinary Portland Cement (OPC) ASTM Type l of Grade: 42.5 with 32 % consistency was used. The initial and final setting time of OPC was 31 minutes and 130 minutes respectively. The Lawerancepur sand was used as fine aggregates.
27-11-2003· DO NOT USE FOUNDRY SAND IN CONCRETE!!!! Foundry sands often contain unreacted magnesium oxide (periclase) or unreacted free lime which can cause significant expansion in the presence of water. The results can be similar to using electric arc steel slag in concrete. Not good! Don't even use it for fill.
Recycled foundry sand can also be used as feedstock for the manufacturing of Portland cement. More Info & Sources Sustainability Victoria – Foundry Sand Recycling Case Study. Brought to you by. Foundation Partner. Stay Connected. Enter your email address and to stay up to date with us!
The sand mould is later broken away from the casting and can be recycled within the foundry or used elsewhere in the production of asphalt or concrete products. Foundries in the UK vary in size and in type with some capable of producing extremely high quality, specialist parts for the aero space mining and automotive industries.

Recycling of Foundry Sand Waste Material for Construction of Concrete Road. Foundry sand is a waste material generated from foundry industry where natural sand is used as a molding material which becomes unsuitable or waste after several cycles of use. It has potential for application in concrete mix for road construction.
In pavement surfaces, foundry sands are also used in hot mix asphalt, and in Portland cement or concrete products. Metalcasting sand also performs extremely well in controlled low-strength material (CLSM), commonly referred to as "flowable fill." Aggregate Substitutes – In these applications, recycled foundry sands substitute for other fine ...
26-01-2021· Beneficial Uses for Spent Foundry Sands EPA's risk assessment for the beneficial uses of spent foundry sands found that that silica-based spent foundry sands produced by iron, steel and aluminum foundries can be safely reused to save energy, reduce the need to mine materials, and reduce costs for both producers and end users.
durability properties of the conventional cementitious concrete due to the addition or replacement of fine sand with used foundry sand in different proportions. However in couple of cases such addition has reported reduction in the values of properties.
