- Correlations of the dispersing capability of NSF and PCE types of superplasticizer and their impacts on cement hydration with the adsorption in fresh cement pastes (2015, background): “On the other hand, the addition of superplasticizers has strong influences on the hydration kinetics of cement, generally observed as a retardation effect [8,13].”
- Rietveld Quantitative Phase Analysis of OPC Clinkers, Cements and Hydration Products (2012, unknown): “This methodology has been applied to anhydrous OPCs (Jansen et al. 2011a) and to OPC pastes (Jansen et al. 2012a,b).”
- Advances in characterizing and understanding the microstructure of cementitious materials (2019, methodology): “…of the phases, in-situ XRD coupled with a Rietveld refinement analysis using an external standard [102] can be preferred and were recently used to better understand the evolution of the chemical balance in the first hours of hydration as well as the effect of admixtures [97,98,100,101,103].”
- Development of an eco-friendly Ultra-High Performance Concrete (UHPC) with efficient cement and mineral admixtures uses (2015, background): “According to the investigation of Jansen [66], complex Ca 2+ ions from pore solution by the superp-lasticizer can touch the polymer absorbed on the nuclei or the anhydrous grain surfaces, which in turn might lead to prevention of the nuclei growth or to the dissolution of the anhydrous grains.”
- Effect of nano-silica on the hydration and microstructure development of Ultra-High Performance Concrete (UHPC) with a low binder amount (2014, unknown): “[38], complex Ca ions from pore solution by the superplasticizer can touch the polymer absorbed on the nuclei or the anhydrous grain surfaces, which in turn might lead to the prevention of the growth of the nuclei or the dissolution of the anhydrous grains.”
- Effects of sulfates on the hydration of Portland cement – A review (2021, methodology): “[134], the presence of PCE, NSF, or LS admixtures approaches the sulfate depletion point from the main hydration peak of alite, as shown in Fig.”
- A study of multiple effects of nano-silica and hybrid fibres on the properties of Ultra-High Performance Fibre Reinforced Concrete (UHPFRC) incorporating waste bottom ash (WBA) (2014, unknown): “According to the investigation of Jansen [60], complex Ca ions from pore solution by the superplasticizer should be the substance that can absorb the polymer on the nuclei or the anhydrous grain surfaces, which in turn might lead to the prevention of the growth of the nuclei or the dissolution of th”
