Hydration mechanisms of ternary Portland cements containing limestone powder and fly ash

K. De Weerdt, +5 more
- 01 Mar 2011 - 
TL;DR: In this article, the effect of minor additions of limestone powder on the properties of fly ash blended cements was investigated using isothermal calorimetry, thermogravimetry (TGA), X-ray diffraction (XRD), scanning electron microscopy (SEM) techniques, and pore solution analysis.
Journal ArticleDOI

Synergy between fly ash and limestone powder in ternary cements

K. De Weerdt, +4 more
- 01 Jan 2011 - 
TL;DR: In this article, the interaction between limestone powder and fly ash in ternary composite cement is investigated, and the synergistic effect of fly ash and limestone powder is confirmed and it translates to improved mechanical properties that persist over time.
Journal ArticleDOI

Impact of the associated cation on chloride binding of Portland cement paste

K. De Weerdt, +6 more
- 01 Feb 2015 - 
TL;DR: In this article, a well hydrated cement paste was exposed to MgCl2, CaCl2 and NaCl solutions at 20°C and the chloride binding capacity of the paste appeared to be related to the pH of the exposure solution.
Journal ArticleDOI

Changes in the phase assemblage of concrete exposed to sea water

Klaartje De Weerdt, +3 more
- 01 Mar 2014 - 
TL;DR: In this paper, the phase changes in an ordinary concrete standing for 10 years in a tidal zone were investigated with a range of techniques, including XRD and TGA analysis of a polished section of the surface near region.
Journal ArticleDOI

Leaching Characterisation and Geochemical Modelling of Minor and Trace Elements Released From Recycled Concrete Aggregates

Christian J. Engelsen, +5 more
- 01 Dec 2010 - 
TL;DR: In this article, the pH dependent release of Cd, Cr, Cu, Mn, Mo, Ni, Pb, V and Zn from different recycled concrete aggregate samples was determined.
