The effect of EDTA, a calcium chelating agent, on the early hydration of Portland cement, C3Sand B-C2S has been studied by solution analysis and electron microscopy. EDTA is a retarder of cement hydration. Under normal conditions of hydration, the silica levels in solution are very low (<0.05 raM) b
