This paper presents the results obtained using the Langavant Calorimeter method on portland cements with different addition materials that are commonly used in the manufacture of commercial cements. The effects of these materials on the hydration heat with respect to a control cement were studied.
With the preparations of C3A and C2(A,F ) obtained after the extraction of silicates with salicylic acid from two technical cements the hydration and its products were examined. All methods used -X-ray diffraction to observe the decrease of C3A and C 2 (A,F) during the hydration, thermoanalytical de
Hydration of portland cement blended with granulated blast furnace slag and rice husk ash in presence of bag house dust has been studied by measuring non-evaporable water contents, heat of hydration and compressive strengths. Analysis of liquid phase for Ca" ion estimations has been made. Hydration
