The influence of ethanolamines on the surface properties of Portland cement pastes

The effect of ethanolamines-monoethanolamine (MEA), diethanolamine (DEA) and triethanolamine (TEA) -on the pore-size distribution 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. Cumulative pore areas and total pore volumes of the samples obtained from nitrogen desorption isotherms were presented along with pore-size distributions calculated using the method of Dollimore and Heal.
