Abstract EN
Cement-based materials were investigated by comparing the strength and microstructure of pastes and mortar containing limestone powder or low quality fly ash.
The compressive strength of the mortar at 28 and 90 d was examined whose microstructures were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), thermogravimetric analysis, and differential thermal analysis (TG-DTA).
The results indicated that the strength of mortar decreased with increasing mineral admixtures.
The limestone powder mainly acted as inert filler and hardly took part in the chemical reaction.
Low quality fly ash may accelerate the formation of hydration products in samples with more chemically bonded water.
This further resulted in a higher degree of cement hydration and denser microstructure, while the overall heat of hydration was reduced.
At the early stage of hydration, low quality fly ash can be considered as an inert material whereas its reactivity at the later stage became high, especially for ground low quality fly ash.
