Ettringite formation in soil-cement interaction process ...

Ettringite is known as one of the important minerals which forms in the process of cement hydration. Sulfate resistance cement can be used to prevent the ettringite formation due to excluding alumina ions in its production process. However, clayey soils might contribute to the formation of ettringite due to the solubility of alumina ions at ...

Sequential combination of nanofiltration and

Additionally, ettringite precipitates could be reused as another method to further reduce the operating cost. These precipitates can be recycled for concrete production because ettringite is a primary constituent of the hydration of concrete based on Portland cement (Gougar et al., 1996; Lee et al., 2005).

Ettringite Formation and the Performance of Concrete

2000-2-28 · ettringite could reduce the protection the air void system affords against freeze-thaw damage (see discussion of freeze-thaw resistance below). Ettringite formed by dissolution and recrystallization in void spaces and cracks is often referred to as “secondary ettringite.” Secondary ettringite is not detrimental to concrete performance.
