Minerals and core sands for foundry applications | LKAB ...
Jul 31, 2020· 1: Is there any reason not to use concrete for a mould for a reasonably small casting if it's left plenty long enough to cure and dry before pouring? I have plenty of concrete readily available and it won't be such a big cast that it'll be an annoyance to break up and dispose of the concrete mould. Foundry sand is available but isn't quite as easy for me to access as concrete.

Nov 17, 2010· In the United States alone, the foundry industry discards up to 10 million tons of sand each year, offering up a plentiful potential resource to replace sand in concrete products. However, because the use of spent foundry sand (SFS) is currently very limited in the concrete industry, this study investigates whether SFS can successfully be used as a sand replacement material in cost …

Aug 13, 2016· Concrete mixes were proportioned to replace 25% and 35% by weight of regular concrete sand with clean/new 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.

Jul 07, 2015· During the mix design for normal concrete the compressive strength required normally dictates the water/cement ratio and the workability gives an indication of the volume of water needed. When designing foamed concrete a target casting density is determined and the water/cement and sand/cement ratios are chosen.
