The effect of accelerators, and in particular lithium salts and citric acid solutions, on the setting time of high alumina cement has been studied using calorimetry, solution analysis and X-ray diffraction techniques. Results are discussed with respect to the ternary CaO-AI203-H20 solubility diagram
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
