Microstructural Features of Railseat Deterioration in Concrete Ties

Autor: L. J. Struble, T. Bakharev

Publikováno v: Journal of Materials in Civil Engineering. 9:146-153

Deterioration has been observed in concrete railroad ties, producing a loss of up to 40 mm at the railseat and leaving a rough surface formed mainly by aggregates. This deterioration occurs largely in cold and wet regions of western Canada and northe

Publikováno v: MRS Proceedings. 370

Wasteforms made by reaction at elevated temperature of a highly alkaline simulated low-level nuclear waste solution, having high sodium ion concentration, with a cementitious blend high in fly ash have been studied. Significant formation of Na-P1 zeo

Llw Solidification Incement -Effect of Dilution

Autor: T. Bakharev, J. F. Young, Leslie J. Struble, A. Katz, R. J. Kirkpatrick, A.R. Brough

Publikováno v: MRS Proceedings. 370

A simulated Low Level nuclear Waste (LLW) solution was tested for long term solidification in a cement-based matrix. The waste is characterized by high pH and high concentrations of sodium, aluminum, nitrate, nitrite, phosphate and carbonate. The eff
