建筑工程专业英语翻译,着急!
OH- ion concentrations in the pore solution were determined by direct
titration against nitric acid using phenolphthalein indicator. The pH values
of the pore solution were calculated from the measured hydroxyl ion concentrations,
Evaporable water on parallel specimens was determined as the loss of
weight per 100 g of unhydrated cement when the specimens were heated
to constant weight at 105℃
