Journal ArticleDOI
Understanding the relationship between geopolymer composition, microstructure and mechanical properties
Peter Duxson,John L. Provis,Grant C. Lukey,Seth W. Mallicoat,Waltraud M. Kriven,Jannie S.J. van Deventer +5 more
TL;DR: In this paper, a mechanistic model accounting for reduced structural reorganization and densification in the microstructure of geopolymer gels with high concentrations of soluble silicon in the activating solution has been proposed.
Journal ArticleDOI
The effect of alkali and Si/Al ratio on the development of mechanical properties of metakaolin-based geopolymers
TL;DR: In this article, the development of Young's modulus of geopolymers between 7 and 28 days was observed to be dependent on alkali, with the Youngs moduli of Na-specimens decreasing at low Si/Al ratio, but increasing at high Si /Al ratio.
Journal ArticleDOI
Stability of Tetragonal ZrO2 Particles in Ceramic Matrices
TL;DR: In this paper, the stability of tetragonal ZrO2 particles in ceramic matrices was considered, with particular reference to Al2O3-ZrO 2 composites and to partially stabilized TZRO 2.
Journal ArticleDOI
Iron release from corroded iron pipes in drinking water distribution systems: effect of dissolved oxygen.
Pankaj Sarin,Vernon L. Snoeyink,J. Bebee,K.K. Jim,M.A. Beckett,Waltraud M. Kriven,Jonathan A. Clement +6 more
TL;DR: It is substantiated that increasing the concentration of oxidants in water and maintaining flowing conditions can reduce the amount of iron release from corroded iron pipes, and that the microstructure and composition of corrosion scales are important parameters that can influence the amounts of iron released from such systems.
Journal ArticleDOI
Iron Corrosion Scales: Model for Scale Growth, Iron Release, and Colored Water Formation
TL;DR: A conceptual model has been developed in this paper to describe the formation and growth of iron scales, and their reactions that lead to colored water problems, which can be used as a basis for changing water quality to minimize colored water formation.
