Geoenvironmental behavior of foundry sand amended mixtures for highway subbases.

The high cost of landfilling and the potential uses of waste foundry sands have prompted research into their beneficial reuse. Roadways have a high potential for large volume usage of the foundry sands. A laboratory testing program was conducted on soil-foundry sand mixtures amended with cement and lime to assess their applicability as highway subbase materials. The mixtures were compacted in t...

Effect of compost-, sand-, or gypsum-amended waste foundry sands on turfgrass yield and nutrient content.

To prevent the 7 to 11 million metric tons of waste foundry sand (WFS) produced annually in the USA from entering landfills, current research is focused on the reuse of WFSs as soil amendments. The effects of different WFS-containing amendments on turfgrass growth and nutrient content were tested by planting perennial ryegrass (Lolium perenne L.) and tall fescue (Schedonorus phoenix (Scop.) Hol...

Ocular effects of exposure to triethylamine in the sand core cold box of a foundry.

OBJECTIVES To assess the acute and chronic ophthalmological effects of triethylamine exposure among foundry workers. METHODS Ocular effects on people currently, previously, and never exposed to triethylamine in a foundry cold box were studied at two points in time. The initial phase included an ocular examination with a slit lamp to assess corneal health, a visual acuity test, and a questionn...
