Abstract: The mineralogy of a soil susceptible to sulfate attack was investigated in detail, with particular attention paid to the sulfate and clay minerals. The soil from north Louisiana suffered sulfate attack when stabilized by ...

Abstract: An amorphous silica (AS) replacing up to 10% of the portland cement by mass in concrete behaved partly as a traditional pozzolan, partly crystallized to quartz and the rest underwent some (crystal) structural reorganization ...

Abstract: A sulfur‐recovery process from phosphogypsum produces a by‐product slag that can potentially be used as aggregate in portland cement concrete. The phase composition and microstructure of samples of slag from a bench‐scale ...

Abstract: Dust from production of steel in an electric arc furnace (EAF) contains a mixture of elements that pose a challenge for both recovery and disposal. This paper relates the leachability of six Canadian EAF dusts in four ...

Abstract: Radioactive liquid waste generated in the closed nuclear fuel cycle is immobilized by fixing the radionuclides in glass by a process known as vitrification. Vitrification is carried out in a joule-heated ceramic melter ...
