The Influence of Slag on the Hydration of Cement –

2013-7-31  The Influence of Slag on the Hydration of Cement. These following conclusions are summarized from the work of Kocaba’s PhD thesis. alite: no influence is shown on the consumption of alite measured by XRD. belite: the substitution of cement by both slags seems to result in a delay in the hydration of belite in the first days.

The influence of steel slag on the hydration of cement ...

2011-2-2  The influence of steel slag, a by-product from the processing of iron to steel, on the hydration of cement during the hydration process of complex binder was studied by calorimetry, X-ray diffraction analysis, and Ca(OH) 2 content determination. The results show that steel slag and cement affect each other’s hydration by changing the hydration environment.

Influence of slag chemistry on the hydration of alkali ...

2011-9-1  The hydration and the microstructure of three alkali activated slags (AAS) with MgO contents between 8 and 13 wt.% are investigated.The slags were hydrated in the presence of two different alkaline activators, NaOH and Na 2 SiO 3 5H 2 O (WG). Higher MgO content of the slag resulted in a faster reaction and higher compressive strengths during the first days.

2018-5-2  It is known from hydration heat analysis that grade I fly ash retards the early-age hydration of cement, but Δ 1 kept positive from 3 days to 28 days and increased with ages, indicating that fly ash promotes the hydration of cement. The higher slope of hydration heat curve of FA-25% after 24 hours compared to that of Cement also proves this point.
