Can waste foundry sand fully replace structural concrete sand? [PDF]
Journal of Material Cycles and Waste Management, 2018 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 ...

Properties of furfuryl alcohol resins for conventional sand moulding and binder jetting applications [PDF]
MATEC Web of Conferences, 2022 This paper compares two commercial acid-cured furfuryl alcohol resins. The first material is used for conventional sand moulding (CSM), while the second material was manufactured for the binder jetting process (BJP) using a Voxeljet VX 1000 printer.

Relationship between casting modulus and grain size in cast A356 aluminium alloys [PDF]
, 2012 Microstructure of Al-Si alloy castings depends most generally on melt preparation and on the cooling rate imposed by the thermal modulus of the component. In the case of Al-Si alloys, emphasis is put during melt preparation on refinement of pro-eutectic (

Dilatometric Characterization of Foundry Sands
Archives of Foundry Engineering, 2012 Dilatometric Characterization of Foundry Sands The goal of this contribution is summary of physical - chemistry properties of usually used foundry silica and no - silica sands in Czech foundries. With the help of dilatometry analysis theoretical assumptions of influence of grain shape and size on dilatation value of sands were confirmed ...

The capability enhancement of aluminium casting process by application of the novel CRIMSON method [PDF]
, 2011 The conventional foundry not only frequently uses batch melting, where the aluminium alloys are melted and held in a furnace for long time, sometimes as long as a complete shift, but also uses the gravity sand casting process where the molten aluminium

Waste foundry sand. Environmental implication and characterization
Geologia USP. Série Científica, 2012 This paper presents the results of analyses using Scanning Electron Microscopy in field samples of waste foundry sand, as well as the results of granulometric, chemical and groundwater analyses. Field data allowed to characterize waste foundry sand and showed that there are elevated concentrations of metals in the groundwater (iron, manganese, boron ...
