replacement of natural sand with used foundry sand up to 30% is desirable, as cost effective. III MATERIALS AND TESTING . The following are the materials to be used in the proposed investigation. a) Foundry Sand b) Cement OPC 43 Grade c) Coarse Aggregate (Crushed Angular Aggregate) d) Fine Aggregate(River sand) FOUNDRY SAND
· Beneficial Uses for Spent Foundry Sands. EPA's risk assessment for the beneficial uses of spent foundry sands found that that silicabased 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. EPA supports the use of silicabased spent foundry .
· This project therefore, proposes a viable option; waste foundry sand. Waste foundry sand is a byproduct of steel industry, which this research aims to prove, can be put to good use. The study involves replacement of conventional sand with waste foundry sand in concrete. Tests cubes were prepared using both conventional sand and waste foundry ...
However, the use of waste in concrete can be a good scope. Locally available industrial waste (Rajkot, Gujarat) used in the study is used foundry sand. Also another waste material used in the study is Fly this paper, the effect of combination of the two industrial byproduct Fly ash and Used Foundry Sand on the Split Tensile Strength of Reactive Powder Concrete is presented. The ...
Water: Potable tap water was used for the preparation of paver blocks and curing of specimens. Foundry Sand: In India, several types of metal industries prefer sand as a casting system. In casting process, they use, recycle and reuse the sand several times but after sometime it is discarded from the foundries which are known as waste foundry sand.

In this project, Rice Husk Ash and Waste Foundry Sand were used in concrete for the replacement of cement and fine aggregate respectively. The most expensive concrete material is the binder (cement) and if such allimportant expensive material is partially replaced with more natural, local and affordable material like RHA will not only take care of waste management but will also reduce the ...
Naik et al. (2004) [8] reported that substitution of part of the sand with used foundry sand in concrete mixes caused a small reduction in strength. R. Bakis (2006) [9] performed a study into the reuse of waste foundry sand in asphalt concrete production by partially replacing a fine aggregate with waste foundry sand.
Used Foundry Sand can be partly replaced for natural sand (fine aggregates) in concrete mixtures to improve durability properties. Foundry Sand is black in color and contain large amount of fines. The materials required for the replacement of fine aggregate are processed to the required specifiions that could match with the properties of fine aggregate to be used in concrete for building.
Foundries successfully recycle and reuse the sand many times in a foundry and the remaining sand that is termed as foundry sand is removed from foundry. This study presents the information about the civil engineering appliions of foundry sand, which is technically sound and is environmentally safe. Use of foundry sand in various engg. appliions can solve the problem of disposal of ...
innovative use of used foundry sand in concrete formulations as a fine aggregate replacement material was tested as an alternative to traditional concrete. The fine aggregate has been replaced by used foundry sand accordingly in the range of 0%, 10%, 30% 50% by weight for M20 grade concrete. Concrete mixtures were produced, tested and compared in terms of workability and .
PREVIOUS RESEARCHREVIEW BASED ON FOUNDRY SAND CONCRETE Naik et al. (1994) investigated the performance of fresh and hardened concrete containing discarded foundry sand in place of fine aggregate. Concrete mixes were proportioned to replace 25% and 35% by weight of regular concrete sand with clean/new foundry sand and used foundry sand. The results of this .
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.

replace sand in concrete products. However, because the use of spent foundry sand (SFS) is currently very limited in the concrete industry, this study investigates whether SFS can successfully be used as a sand replacement material in costeffective, green, selfconsolidating concrete (SCC). In the study, SCC

2 parts silica sand (The same stuff you use for your GreenSand) parts perlite (Pure not a blend of other things meant for plants. "NOT" Vermiculite either!) 2 parts fireclay or Well drillers mud (Bentonite Clay) You want to mix the dry parts thoroughly, it will take a while for the clay to bond to the sand. You could use a cement
Use of used foundry sand in different engineering appliions can solve the problem of disposal of used foundry sand and other functions. Foundry sand exists primarily of silica sand, coated with a thin film of burnt carbon, residual and dust. To enhance the strength and other durability factors foundry sand can be used in concrete.
properties of foundry sand for use in Portland cement and concrete, hot mix asphalt, road subbase layers, embankments, and flowable fill. Recent studies addressing environmental concerns of using foundry sand, an industrial byproduct, as a construction material are reviewed. Some case studies are presented to demonstrate
Although foundry sand can be an excellent feedstock for Portland cement manufacturing, transportation distances may be an impediment to sourcing more foundry sands for Portland cement kilns. There are only 118 cement kilns in the United States, some of which own adjacent quarries where limestone and other aggregates are processed for cement production.
