متن کاملSEM investigation of microstructures in hydration products of portland cement
Portland cement is the one of the main ingredients in the manufacture of many building materials include concrete composites. The phase composition of hydration products is controlled by means of XRD and DTA/TG analysis. Observations of phase changes and microstructure of maturing cement pastes can also be observed using scanning electron microscopy (SEM) techniques combined with chemical analy...
متن کاملInteraction of tartaric acid during hydration of Portland cement
Hydration of Ordinary Portland cement (OPC) in the presence of tartaric acid has been studied by using different techniques. Calorimetric studies have shown a rapid enhanced heat evolution within 5 min of hydration in presence of 1.0 wt% tartaric acid with a strong retardation of silicate phase hydration. DSC and X-ray diffraction studies have confirmed the formation of calcium tartarate hydrat...
متن کاملMeasurements and Predictions of Heat of Hydration of Portland Cement Using Isothermal Conduction Calorimetry
Two industrial ASTM Portland cements were carefully tested for heat of hydration (HOH) continuously up to 7 days at 23o C using isothermal conduction calorimetry in accordance to ASTM C1702. Internal and external mixing procedures were implemented. The results for HOH measurements at 7 days using isothermal calorimetry were compared to those obtained through heat of solution method (ASTM C186)....
