Journal ArticleDOI
Effect of polycarboxylate ether superplasticizer (PCE) on dynamic yield stress, thixotropy and flocculation state of fresh cement pastes in consideration of the Critical Micelle Concentration (CMC)
TL;DR: In this paper, the effect of polycarboxylate ether surperplasticizer (PCE) addition on thixotropy and flocculation state has not gained enough attention.
Journal ArticleDOI
Structural build-up of cementitious paste with nano-Fe3O4 under time-varying magnetic fields
TL;DR: In this article, the structural build-up of cementitious paste with nano-Fe3O4 under time-varying magnetic fields was experimentally investigated using small amplitude oscillatory shear (SAOS) technique.
Journal ArticleDOI
Structure-property relationships for polycarboxylate ether superplasticizers by means of RAFT polymerization.
Metwally Ezzat,Xiaowen Xu,Khadija El Cheikh,Karel Lesage,Richard Hoogenboom,Geert De Schutter +5 more
TL;DR: It is found that the shorter the side chain, the lower the yield stress and the higher the dispersion of cement pastes but to a limited effect, and the charge types have a major influence on the performance of superplasticizers.
Journal ArticleDOI
Rheological behavior of cement paste with nano-Fe3O4 under magnetic field : magneto-rheological responses and conceptual calculations
Dengwu Jiao,Dengwu Jiao,Karel Lesage,Mert Yücel Yardımcı,Khadija El Cheikh,Caijun Shi,Geert De Schutter +6 more
TL;DR: In this paper, the authors investigated the magneto-rheological responses of cement paste with nano-Fe3O4 particles and found that the particles have a potential to move to form magnetic clusters when a magnetic field is applied, which creates a sort of agitation effect breaking down the early C-S-H links between cement particles, and the corresponding suspensions exhibit liquid-like behavior immediately after applying the magnetic field.
Journal ArticleDOI
Structural evolution of cement paste with nano-Fe3O4 under magnetic field - Effect of concentration and particle size of nano-Fe3O4
Dengwu Jiao,Dengwu Jiao,Karel Lesage,Mert Yücel Yardımcı,Khadija El Cheikh,Caijun Shi,Geert De Schutter +6 more
TL;DR: In this article, the effects of concentration and particle size of nano-Fe3O4 particles on the evolution of structural build-up of cementitious paste under magnetic field were experimentally investigated and then verified by theoretical calculations.
