Flowable fill using waste foundry sand: A substitute for compacted or stabilized soil
- Purdue Univ., West Lafayette, IN (United States). School of Civil Engineering
Flowable fill is generally a mixture of sand, fly ash, a small amount of cement, and water. Sand is the major component of most flowable fill mixes; consequently, using a waste material as a substitute for natural sand results in the beneficial use of the waste material. Waste foundry sand (WFS) was used as a fine aggregate in this study. Three green sands from ferrous foundries and two class F fly ashes were used. The flow behavior, hardening characteristics, ultimate strength behavior, and permeability characteristics of flowable fill were investigated. The penetration resistance necessary to sustain walkability as the fresh flowable fill hardens was determined. The pH of pore solution of hardened flowable fill indicated that the potential for corrosivity is low. The toxicity tests indicated that some WFSs are environmentally safe.
