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 and used foundry sand. Concrete performance was evaluated with respect to compressive strength, tensile strength, and modulus of elasticity. At 28-day age, concrete containing used foundry sand showed about 20-30% lower values than concrete without used foundry sand. But concrete containing25% and 35% clean/new foundry sand gave ...
Siddique et al. present the results of an experimental investigation carried out to evaluate the mechanical properties of concrete mixtures in which fine aggregate (regular sand) was partially replaced with used-foundry sand (UFS). In this study, fine aggregate was replaced with three percentages (10%, 20%, and 30%) of UFS by weight.
18 The Open Waste Management Journal, 2010, 3, 18-25 Open Access Used Foundry Sand in Cement Mortars and Concrete Production Saveria Monosi, Daniela Sani* and Francesca Tittarelli Università Politecnica delle Marche, Dipartimento di Fisica, Ingegneria dei Materiali e del Territorio (FIMET), Italy Abstract: Used foundry sands represent the highest amount of solid wastes generated by foundries.
At 28-day age, concrete containing used foundry sand showed about 20-30% lower values than concrete without used foundry sand. But concrete containing 25% and 35% clean/new foundry sand gave ...
12%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 only be used for modest sand replacements, based mostly on evidence on concrete with clay-bound FS (greensand). …

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 ...
Abstract This state of art review represents the development in the field of utilization of used foundry sand in cementitious concrete. The paper reviews the u…
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.
At 28‐day age, concrete containing used foundry sand showed about 20–30% lower values than concrete without used foundry sand. But concrete containing 25% and 35% clean/new foundry sand gave almost the same compressive strength as that of the control mix.
foundry sand concrete. To know the behavior of compressive and split tensile strength of foundry sand. To analyse the different areas of civil engineering in which Foundry Sand can be used efficiently. To obtain the above objectives of the experimental work, the test programmer is planned as ...
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 ...
Use of waste foundry sand in concrete reduces the production of waste through metal industries; it is an eco friendly building material. REFERENCES Abichou T.Benson, C. Edil (1998) Database on beneficial reuse of foundry byproducts, Recycled …
Foundry Sand - Asphalt Concrete INTRODUCTION In the United States, asphalt concrete is used to cover over 2 million miles of roadway, accounting for over 94 percent of all pavements.(1) Foundry sand has been used successfully as a partial replacement for the fine aggregate in hot mix asphalt pavements (HMA).(1;2;3;4) Some general material characteristics must be met when using foundry sand in ...
Concrete mixes were proportioned to replace 25% and 35% by weight of regular concrete sand Foundry sand used for the centuries as a molding casting with clean/new foundry sand and used foundry sand. The material because it's high thermal conductivity. The results of this investigation showed that mix containing 25% physical and chemical ...
