Use Of Coal Combustion Residues And Foundry Sands In Flowable Fill, Subnahmanya T. Bhat, C. W. Lovell
JTRP Technical Reports
The purpose of the present study is to investigate the use of waste foundry sand in flowable fill. However, the concepts developed are applicable to flowable fills containing any type of sand. Even though the flowable fill is presently popular as a trench filling material, this study addresses a much broader perspective in order to be able to develop uses of this material in geotechnical applications. In this research, only green sands were taken. The fly ash used was class F type. Flowability, hardening characteristics and 28-day unconfined compressive strength are studied. A rational approach the mix design of flowable …

Environmental Bioassay Evaluation Of Foundry Waste Residuals, Kenneth Chad Bastian, James E. Alleman
JTRP Technical Reports
Although the constructive reuse of foundry residuals represents a decidedly beneficial goal with distinct economic and environmental benefits, potential end-users are nonetheless reluctant to use these residuals, given an inherent concern about potential unforeseen environmental liabilities. Results of foundry residual leachate characterization to date strongly suggest that many ferrous foundries are discarding sands whose quality is fully amenable to their future use with embankment construction and related high-volume highway development activities. In order to provide additional assurance as to the environmental impact of foundry residual reuse, the MicrotoxTM bioassay has been used to quantify the response of living organisms (e.g., …
