Immobilization of Radioactive Waste in Fly Ash Based Geopolymers
نویسنده
چکیده
The low-level salt waste (LAW) associated with the production of nuclear materials at US Department of Energy (DOE) facilities will be disposed of in shallow land burial sites managed by the DOE. Two of the primary contaminants of interest are Tc-99 and I-129, both soluble and long-lived radionuclides. Cs-137, a short-lived, strong gamma emitter is also a soluble contaminant of concern. In addition to radionuclides, the waste salt solutions can contain toxic quantities of metals as defined by the US Environmental Protection Agency (EPA) Resource Conservation and Recovery Act (RCRA).

Study of Fly Ash Geopolymer Based Composites with Polyester Waste Addition
In the present work, fly ash geopolymer based composites including polyester (PES) waste were studied. Specimens of three compositions were prepared: (a) fly ash geopolymer with 5% PES waste; (b) fly ash geopolymer mortar with 5% PES waste; (c) fly ash geopolymer mortar with 6.25% PES waste. Compressive and bending strength measurements, water absorption test and determination of thermal conduc...

In this work, three samples of municipal solid waste incinerators fly ash (MSWI-FA) have been stabilized in systems containing coal fly ash to create geopolymers through a polycondensation reaction. Monolithic products have been obtained with both MSWI fly ash as received and after the partial removal of chloride and sulfate by water washing. The polycondensation products have been characterize...
متن کاملModeling the Formation of Geopolymers
Geopolymers are a class of X-ray amorphous alkali aluminosilicate gel binder materials with potential applications in a wide range of areas. In particular, geopolymers can provide significant improvements over traditional Portland cement technology in applications requiring resistance to acid or salt attack, or thermal stability at temperatures up to 1000°C. The quasi-zeolitic nature of some of...
متن کاملWaste Stabilization/solidification (s/s) Using Fly Ash-based Geopolymers. Influence of Carbonation on the S/s of an Eaf Dust
The effect of the curing in a carbonated ambient of the solids obtained after the stabilization/solidification (S/S) of metallurgical waste using geopolymerization technology is described in this paper. The electric arc furnace (EAF) dust used to stabilize contains hazardous metals such as Pb, Cd, Cr or Zn. Different geopolymeric agents as potassium hydroxide, potassium silicate, metakaolin and...
متن کاملEffect of Fly Ash Fineness on Sorption Properties of Geopolymers Based On Liquid Glass
Abstract—Fly ash (FA) thanks to the significant presence of SiO2 and Al2O3 as the main components is a potential raw material for geopolymers production. Mechanical activation is a method for improving FA reactivity and also the porosity of final mixture; those parameters can be analysed through sorption properties. They have direct impact on the durability of fly ash based geopolymer mortars. ...
