Foundry Sand Facts for Civil Engineers- [May 2004, 80-pages] Foundry sand production is nearly six to 10 million tons annually. Like many waste products, foundry sand has beneficial applications to other industries. The purpose of this document is to provide technical information about the potential civil engineering applications of foundry sand.

to concrete. The main contents of foundry sand are silica sand, burnt carbon, with residue and dust. (2)(3). To increase the strength and other durability factors of concrete foundry sand can be used as a partial or total replacement of fine aggregates in concrete due to its fine in nature.
However, the use of fly ash leads to a reduction in early strength of concrete. Therefore, the concurrent use of quarry dust and fly ash in concrete will lead to the benefits of using such materials being added and some of the undesirable effects being negated. Foundry sand
Foundry sand (FS) waste creates a serious solid waste management problem worldwide due to the high volumes produced, necessitating alternatives to landfilling. A possible route is its use in concrete; however, the current consensus is that FS can

The metal casting industry generates spent foundry sands. Foundries purchase new, sand to make casting molds, and the sand is reused numerous times within the foundry. This reuse eventually renders the sand unsuitable for use in casting molds, and a portion of the sand is continuously removed and replaced with sand.
foundry sand can be used in asphalt mixtures and concrete precast products without structural function in accordance with the laws of each state (Santa Catarina Resolution CONSEMA 011/2008 and Decisão da diretoria No 152/2007/C/E. This study shows the use of spent foundry sand as aggregate to manufacture paving
In the current study, used foundry sand (UFS) and spent garnet sand (SGS) are used as a partial and full replacement to sand in concrete production. Design/methodology/approach The objective of the work is to develop non-conventional concrete by replacing river sand with a combination of UFS (constant 20Wt.% replacement) and SGS at various ...
Studies showed cement can replace with by fly ash in geopolymer concrete. GGBS can use upto 50–70%, Waste foundry sand upto 30–50%, 25% fly ash and 75% GGBS for better strength results ...
fine aggregate with used-foundry sand is most suitable for asphalt concrete mixtures. Additionally, reported is that used-foundry sand did not affect the environment around the deposition. Yuksel et al. [10] used both bottom ash and non-ground blast furnace slag as 10%, 20%, 30%, 40% and 50% fine aggregate replacement, respectively.
Natural crushed stone aggregate (based on limestone) and river sand from a local source were used. The natural river sand 0–4 mm, 4–16, and 16–32 mm natural crushed stones were used as aggregates. The properties of aggregates used in this research are given in Figure 2.
In this project, fine aggregate is partially replaced with foundry sand (20,30, 40%), and basalt fiber used to improve the both compression and tensile strength of concrete (2,2.5,3%).Decided to ...
The amount of water absorbed per unit area for concrete containing different amounts of waste foundry sand (WFS) versus square root of time at the ages of 1, 7, 28 and 90 days of curing, is shown in Fig. 1, Fig. 2, Fig. 3, Fig. 4 respectively. Generally, there is higher amount of water uptake with the increase in foundry sand content at the end of the test period.
Sand can be used as a road base which is a protective layer underneath all roads; Industrial sand is used to make glass, as foundry sand and as abrasive sand. One creative usage of sand is serving as a candle holder. We can try putting some sand before pouring tea light or any candle in a glass.
2 parts silica sand (The same stuff you use for your GreenSand) 1.5 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
2. Does EPA support beneficial uses of silica-based spent foundry sand? Based on the conclusions of the risk assessment and the available environmental and economic benefits, the EPA supports the beneficial use of silica-based spent foundry sands specifically from iron, steel and aluminum foundries, when used in manufactured soils, soil-less potting media, and roadway …

is experiment the suitability to use beach/sea sand as a substitute for river sand as fine aggregate for concrete. Experimental results show that the washed sea sand is ideal for concrete and plastering activities. When compared with river sand concrete, 50 and replacement of sea sand with
Foundry sand is high quality silica sand which is a by-product of ferrous and nonferrous metal casting industries. Foundry sand is produced by five different foundry classes. The ferrous foundries produce the most of the percentage of sand while aluminium, copper, brass and bronze produce the rest. Ferrous (iron and steel) industries account ...
compacting concrete. Use of iron-foundry baghouse dust material as a partial replacement of Class C fly ash and sand did not reduce the use of chemical admixtures and, therefore, did not help reduce the cost of SCC directly. The use of foundry dust increased the air content and decreased the long-term strength of SCC.

Foundry sand is an industrial waste material generated from the foundry industries spreded all over the country. It is a natural sand which is used as a molding material in the ferrous and nonferrous metal casting industries. This sand is typically recycled and reused through many production cycles.

Abstract. This report provides technical data regarding the reuse of excess foundry sand. The report addresses three topics: (1) a statistically sound evaluation of the characterization of foundry sand, (2) a laboratory investigation to qualify excess foundry sand as a major component in controlled low-strength material (CLSM), and (3) the identification of the best methods for using foundry ...
5. Concrete containing weathered sand and concrete containing burnt black sand has resulted in lower strength at 28 days of curing i.e., 27.76N/mm2 and 28.05 N/mm2 respectively compared to control mix of strength 42.292N/mm2, this is due to higher water absorption of foundry waste sand.
The metal casting industry generates spent foundry sands. Foundries purchase new, sand to make casting molds, and the sand is reused numerous times within the foundry. This reuse eventually renders the sand unsuitable for use in casting molds, and a portion of the sand is continuously removed and replaced with sand.
the extent of natural sand replacement in concrete with WFS on the properties of concrete requires further investigation. Foundry industries work with ferrous metals (steel, iron, and stainless steel)
This paper reports results on the properties of concrete containing waste foundry sand (WFS). Fine aggregate was replaced with 0- WFS. The water to cement for all mixes was kept constant. Fresh and hardened properties of concrete were investigated. Hardened properties included water absorption, strength, ultrasonic pulse velocity (UPV) and length change.
