This paper presents some recent research on the microstructural development during alkaline activation of slag pastes. Pastes of different slags activated with a range of activators have been prepared and some preliminary results from the study of the pastes activated with sodium hydroxide and water

The combined effect of sodium lignosulfonate and sodium carbonate on the C4AF hydration was examined by DTG and TG curves and by zeta potential measurements. In the presence of lignosulfonate-carbonate systems the C4AF hydration is completely blocked. The higher the percentage of admixtures, the lon
In this study, the factors which control carbonate cementation have been examined and several hypotheses developed to explain their interaction. These factors include the pressure, concentration, temperature and velocity of the carbonating gas as well as the thickness, temperature, gas permeability,
This paper examines the early hydration of alkali-slag cements activated by different sodium compounds, such as NaOH, Na&O,, Na$iO,.SH,O, Na,PO.,, N%HPO, and NaF, at 25 and 50ยฐC. A conduction calorimeter was used to monitor hydration kinetics. It was found that the initial pH of activator solution h
