The influence of ethanolamines on the hydration and mechanical properties of Portland cement

Heren, Z. / Ölmez, H.

The effect of ethanolamines - monoethanolamine (MEA), diethanolamine (DEA), triethanolamine (TEA) - on the hydration, mechanical and surface properties of the white Portland cement pastes (white PC) has been investigated. The cement pastes with and without admixtures were cured at various hydration times ranging from 1 day to 90 days. Hydration development of cement pastes were followed by setting times, flexural and compressive strengths, specific surface area measurements and thermal analysis techniques. The measurements showed that all these admixtures retard the hydration of white Portland cement in order TEA>DEA>MEA.
