Other concrete mixes were proportioned to replace 25 and 35 by weight of regular concrete sand with cleannew foundry sand and used foundry sand. Concrete performance was evaluated with respect to compressive strength, tensile strength, and modulus of elasticity.
2017-8-27of concrete containing used foundry sand. Concrete was produced by replacing natural sand with UFS in various percentages 10, 20, 30 and 40. Based on the test results they concluded that i workability goes on reducing with increase in UFS content ii At 28-days, Compressive strength, splitting tensile strength and flexural tensile ...
Concrete mixes were proportioned to replace 25 and 35 by weight of regular concrete sand with cleannew foundry sand and used foundry sand. The results of this investigation showed that mix containing 25 discarded foundry sand showed about 10 higher compressive strength at 28 days than the mix containing 35 discarded foundry sand.
2008-6-5Methodology to evaluate used foundry sand as concrete aggregate Sbrighi Neto, C.Tango, C.E.S. Lotti, F. Quarcioni, V.A. IPT Technological Research Institute of Sao Paula State - Brazil Abstract Nowadays used foundry sand becomes, more and more, an environmental problem because it is not easy to flnd a safety way to dispose it.

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.
Used foundry sand UFS Fig. 4.1 is a discarded material coming from ferrous iron and steel and nonferrous copper, aluminium, and brass metal-casting industry to create molds and cores.About 1 ton of foundry sand for each ton of iron or steel casting produced is used Siddique and Noumowec, 2008.Typically, suppliers of the automotive industry and its parts are the major generators of ...

Key Words concrete, used foundry sand, waste ceramic tiles, coarse aggregates, fine sand, compressive strength, split tensile strength, modulus of elasticity. 1. INTRODUCTION Foundry sand is a sand that when moistened and
2017-4-7foundry sand and coarse aggregate with used recycled coarse aggregate to produce low cost and eco-friendly concrete. The main objectives of the present experimental work are discussed below 1 To find the efficiency of the Foundry Sand and recycled aggregate for civil constructions.
UTILIZATION OF USED FOUNDRY SAND IN CONCRETE. The performance of fresh and hardened concrete containing discarded foundry sands in place of fine aggregate was investigated. The details are described of the study in which a control concrete mix was proportioned to achieve a 28-day compressive strength of 38 MPa, and other mixes were proportioned ...

2016-11-7Foundry sand Foundry sand is high class silica sand with identical material characteristics. It is a by-product of ferrous and non-ferrous metal casting industries, where sand has been used for molding material because of its thermal conductivity. It is a by-product from metal castings industries.
2015-6-25500 micron is used in the glass industries. Sand size 1.18mm to 600 micron can be used in making concrete mix as the partial replacement of fine aggregate. Nearly about 200 tones of silica sand is obtained daily after washing the raw material. Sometimes it is used in the glass factories otherwise they dump them back into the mines. II.
Foundry sand consists primarily of clean, uniformly sized, high-quality silica sand or lake sand that is bonded to form molds for ferrous iron and steel and nonferrous copper, aluminum, brass metal castings. Although these sands are clean prio...

2015-6-26C. Used Foundry Sand Used foundry sand which is used in this experimental work was collected from Rajkot. Used ferrous foundry sand was used for casting of mild steel and it was chemically bonded sand. Specific gravity and water absorption of this foundry sand is 2.38 and 0.43 percent, respectively. Fineness modulus of used foundry sand is 2.05 ...
2017-9-15waste foundry sand from Ms. Nandhini Castings, Coimbatore, was used as partial replacement of fine aggregate. Foundry sand with specific gravity 2.51 and water absorption 1.55 was used. Table 1 provides the chemical composition of foundry sand. A control mixture F0 was designed as per BIS 10262 200920 to have 28 days compressive strength of
Foundry sand is clean, uniformly sized, high quality silica sand, used in foundry casting processes. The sand is bonded to form molds or patterns used for ferrous iron and steel and non-ferrous copper, aluminum, brass metal castings. Shake-out sand from completed metal casting are often reclaimed back into the foundry sand process.

The spent foundry sand is either recycled in non-foundry applications or landfilled. In 2007, the American Foundry Society estimated Exit that less than 30 percent of the 10 million tons of spent foundry sands generated annually are recycled. EPA believes a greater percentage of spent foundry sand can be safely and economically reused.
