2016Effect of Addition of HYPR and CABP on the Physiochemical and Mechanical Properties of Cement PastesMaha Rabea Abu-Serea 
2008The effect of addition of Zn, Cu, Pb and Cr chlorides as admixtures on the hydration reaction of the system 3CaO¢Al2O3-gypsum with molar ratio 1:3 was studied. Di®erent ratios of each salt were used, namely 0.5%, 2% and 4% by weight of the solid mixture. Hydration reaction was carried out at 35±C for various time intervals from 0.5 h to up to 7 d. Hydration rate of the system 3CaO¢Al2O3-CaSO4¢2H2O in absence and presence of di®erent salts was studied via the determination of the combined water contents. X-ray di®raction analysis showed that the ettringite was the only hydration product formed in the di®erent mixes. The hydration products were investigated by scanning electron microscopy (SEM) and thermal gravimetric analysis. The results indicated that the rate of formation of ettringite and its microstructure depend on the admixture and its dosage.Maha Rabea Abu-Serea ; E. A. Kishar ; Eisa A. Hekal
