6. Experimental Study of De-icing Salt-frost Scaling in Concrete with Low-calcium Fly Ash or Slag : Influence of Drying and Carbonation, and Air Content
Abstract : In order to reduce the net climate impact of concrete production, it is necessary for the industry to undertake several actions. Among these is to include fly ash and slag as supplementary cementitious materials. Accordingly, this project has studied concrete containing low-calcium fly ash or ground-granulated blast-furnace slag. READ MORE

7. Experimental studies of sorption and transport of moisture in cement based materials with supplementary cementitious materials
Abstract : Most deterioration processes in cement based materials are closely related to moisture sorption and moisture transport properties. Therefore, it is important to study these properties, both theoretically and practically. This work is an experimental investigation in this field. READ MORE

8. Hydration, pore structure, and related moisture properties of fly ash blended cement-based materials : Experimental methods and laboratory measurements
Abstract : Cement-based materials, such as mortar and concrete, are the most employed construction materials in the world. Cement is an important component; it reacts with water to form a glue, called cement paste, which causes the material to harden. Today, cement production accounts for a significant portion of the world’s annual carbon dioxide emissions. READ MORE

9. Portland Cement Clinker - Composition and Hydration
Abstract : The crystal structures of the main Portland cement clinker phases are reviewed and two anion centered models of Ca3SiO5 and Ca2SiO4 are presented. The effects of minor elements on the clinkering process, and on the qualitative and quantitative phase compositions of Portland cement clinker are discussed. READ MORE

10. Influence of solid solutions on the properties of some apatite-type calcium salts relevant to the production of phosphate and silicate cements
Abstract : The effects of non-stoichiometry and isomorphic substitutions on the properties of some apatite-type compounds were investigated. These investigations were performed both in the fields of Portland cement chemistry and apatitic calcium phosphate-based biocements. READ MORE
