The goal of this research is to analyze the use of spent foundry sand (SFS) and foundry exhausted dust (ED) in the making of interlocking concrete paving blocks. These blocks have been made with foundry sand waste as aggregate and this element has been substituted partially by 0, 5, 10, 15 and 20% with exhausted dust.

Sep 19, 2017Sand casting using green sand is quick and inexpensive since the sand can be reused. The downside is that the sand is a soft mold and can collapse or shift during casting, leaving an unusable cast. However, the process is reliable enough that it has survived for centuries and is still used today. Patriot Foundry is a nationally trusted non

Spent Foundry Sand (SFS) generation is intrinsic to metal casting processes. Most ferrous foundries use sand moulds and cores for casting, which are discarded after pouring (lost mould technique). This generates large amounts of waste sand, representing approximately 6085% of total solid waste from foundry.

Dec 03, 2010The feasibility of recycling spent foundry sand in clay bricks was assessed in laboratory, pilot line and industrial trials, using naturally occurring sand as a reference. Raw materials were analyzed by Xray fluorescence, Xray diffraction, particle size distribution, and leaching and combined to produce bodies containing up to 35% wt. sand.

A dry method of conditioning spent foundry sand is disclosed. After having sized the sand and removal of tramp metallic elements, the sand is subjected to a sequence of squeezing under a highstress low kinetic energy system for a period of 530 minutes, and then propelled against a target with highkenitic energy in the presence of a suction for several minutes.

Spent foundry sand (SFS) from cast iron industry mixed with loess was characterized to recycle spent foundry sand as ceramic support materials. Since SFS mostly consists of sand including binding agents and residue [1], it was used as permeable media, and loess, which has highly adsorptive and reactive properties, was used as support materials Leaching tests such as Korean Leaching Test (KLT

This paper presents the application of Taguchi approach to obtain optimal mix proportion for Self Compacting Concrete (SCC) containing spent foundry sand and Msand. Spent foundry sand is used as a partial replacement for Msand. The SCC mix has seven control factors namely, Coarse aggregate, Msand with Spent Foundry sand, Cement, Fly ash, Water, Super plasticizer and Viscosity

Jan 09, 2015The sand is reused numerous times within the foundry operation itself. However, over time the sands become unusable and are referred to as spent foundry sands, according to EPA. The spent foundry sands are then reused in a number of ways, including as an ingredient in potting soil and as a foundation layer in roadway construction.
