Aqueous reactivity of glassy industrial byproducts in alternative cementitious systems
… silica-, alumina-, lime-, and/or alkali-rich industrial byproducts (IBs) exhibit the properties necessary to achieve emissions reductions while preserving final product attributes expected of cementitious binders. Research and industry have both focused primarily on metakaolin and IBs such as …

Evaluating Steel Byproducts and Natural Minerals for Phosphate Adsorption from Agricultural Subsurface Drainage
… P adsorption capacities of natural minerals and industrial byproducts, including limestone, zeolite, calcite, steel slag, iron filings, and steel byproducts. Steel byproducts are a lowcost, readily available material that has high P adsorption potential. The steel byproducts included small chips, …

Drinking Water Treatment Waste as an Alternative for Internal Curing and Cement Replacement in Concrete
… footprint. Concrete incorporates many recycled industrial byproducts such as fly ash and blast furnace slag which helps reduce the quantity of landfilled materials while reducing CO2. The large volume of drinking water treatment waste generated by each metropolitan city has motivated many to …

Evaluating Filter Materials for E. Coli Removal from Stormwater
… stormwater using low-cost filter materials. Two industrial byproducts (steel slag and steel chips) and two natural minerals (zeolite and limestone) with three different sizes (0.5-1 mm, 1-2 mm, and 2-4 mm) were chosen to investigate the potential of these materials as filter media for E. coli …

Chemically Induced Phytoextraction of Lead (Pb) Contaminated Soil by Switchgrass (Panicum virgatum L.)
… with lead (Pb) from human activities including industrial byproducts create an environmental and human health risk. Phytoextraction through chemical acquisition of Pb in soils offer a potentially cost effective and ecologically driven approach to remediation. Switchgrass (<em>Panicum virgatum …

Understanding the role of calcium on the reaction mechanism of geopolymer cements through addition of nucleation seeds
… use. It is made from minimally processed industrial byproducts (fly ash, slag) activated by a low concentration alkaline solution (Na, K) and cured at room temperature. The use of low concentration alkaline activators (2 M), unlike the high concentration used for conventional geopolymer …

Effects of Long-Term Exposure of Normal C57BL/6J Inbred Mice to 17β-Estradiol on Gene Expression in Lymphocytes: mRNA Analysis of Lymphokines and bcl-2/fas
… estrogenic chemical exposure (e.g. pesticides, industrial byproducts) and phytoestrogens (e.g. soybeans). It has long been recognized that estrogen, a female sex hormone, functions not only on the reproductive system, but also on various other systems including the immune system. Estrogens are …

Elevated temperatures in waste containment facilities
… (MSW), construction demolition debris (CDD), industrial byproducts, and many other wastes are landfilled in waste containment facilities. A number of factors can lead to elevated temperatures and thus present a hazard to the public health and safety. For instance, MSW landfills can produce …

Setting and nanostructure of slag-fly ash binders
… cement (OPC). The precursors for SFB are industrial byproducts, namely slag and fly ash. The inexpensive nature of the precursors offer SFB a cost-competitive edge over OPC and makes them an attractive alternative binder. Calcium silicate hydrate type gels (C-S-H, C-A-S-H, and C-N-A-S-H) …
