摘要：

When Portland cement is contacted with water, calcium ion is rapidly leached from the solid to form calcium hydroxide solution but only traces of silica are found in the aqueous phase. It is proposed that the hydrated, calcium-depleted surface of grains consists of low molecular mass silicic acids and that these interact with dissolved hydroxylated calcium species. An attempt is made to explain the mechanisms by which the morphology (observed most clearly in dilute phases) arises and to relate this to the mechanical properties of dense, hydrated cement paste.
