Strength-promoting mechanism of alkanolamines on limestone ...

This paper reports the strength-promoting mechanism of alkanolamines on limestone-calcined clay cement (LC 3).The hydration kinetics, phase formation and microstructure of LC 3 with triethanolamine (TEA) or triisopropanolamine (TIPA) were investigated. TEA enhanced the strength of LC 3, while TIPA was effective at 28 days, and a correct sulfate addition promoted their effects.

Limestone - Wikipedia

Limestone is a common type of carbonate sedimentary rock.It is composed mostly of the minerals calcite and aragonite, which are different crystal forms of calcium carbonate (CaCO 3).Limestone forms when these minerals precipitate out of water containing dissolved calcium. This can take place through both biological and nonbiological processes, though biological processes have likely been more ...
