sand after the casting process of metal is reuse for many times but when it cannot be longer used it is removed from sand". In India, an estimated 2 million tons of waste foundry sand is produced every year. Use of waste foundry sand as a partial or total replacement for fine aggregate in
of beneficial utilization of used foundry sand in concrete as a partial replacement of regular sand by studying properties of both fresh and hardened concrete. An extensive literature search was undertaken and tests were conducted on by-product samples to determine their physical properties to evaluate the possible uses (Naik et al. 1991, 1992).
Used foundry sand is an industrial waste material from foundry industries. These materials are normally used for land filling of low lying areas. These can also be used as a partial replacement to fine aggregates in concrete. Used foundry sand is pulverized to get the pulverized used foundry sand (PUFS).By pulverizing the used foundry sand we will
Advances in Materials Science and Engineering is a peer-reviewed, Open Access journal that publishes original research articles as well as review articles in all areas of materials science and engineering. ... Mechanical and Durability Properties of Concrete Made with Used Foundry 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.
Jul 22, 2014· Saveria Monosi, Daniela Sani and Francesca Tittarelli, "Used foundry sand in cement mortars and concrete production", The Open Waste Management Journal, Vol.3, ISSN 1876-4002, pg.18-25, 2010. 
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.
USED FOUNDRY SAND FOR APPLICATIONS IN CEMENT CONCRETE Used foundry sand can be effectively utilised in the production of concretes of different grades and characteristics. A number of researches were conducted on concretes with different grades with different proportions of used foundry sand. Some significant research excerpts are described below.
C. 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 …
Spent foundry sand, when used as partial replacement of fine aggregate in concrete, has been shown to improve the mechanical properties of concrete  . Existing studies, however, limit ...
by foundry sand in 10, 20, 30 & 40% by weight in concrete. From their test they concluded that Maximum compressive strength is obtained at 30% replacement and then decreases. By Tarun R Naik et al.,  They investigated on the topic of îUtilization of Used Foundry Sand in Concrete ï. Here they tested the values of
Waste foundry sand is one such alternative to regular sand, constituent of concrete. However, waste foundry sand is a lower quality material and has some adverse effects on concrete properties when used in high or complete replacement to sand, the majority of research studies showed that, yet it can be used to make structural concrete as well.
