✦ Synopsis

A pore solution study was undertaken to provide additional understanding of the hydration behavior of high-calcium ¯y ash in ¯y-ash± water pastes. Three sources of ¯y ash were selected from a previous study on the basis of their hydration behavior, particularly their ability to form ettringite. Pastes were made from each ¯y ash and water, and pore solutions were expressed at varying times and were analyzed for the following ions: SO
