| 摘要： | Sands, binders, and additives are used to form molds and cores of metal castings. The sands are reused a number of times but ultimately are sufficiently altered to require being discarded. A laboratory study of a variety of waste sands from Indiana foundries is reported. Most of the wastes were generated from a green sand molding of gray iron products. Other sands were from chemically bonded and shell molding processes. The suitability of waste sands for use as a fine aggregate in asphalt concrete has been examined by replacing some portions of conventional aggregates with a particular waste foundry sand. A replacement level of 15% was found to be suitable for this case. |
