The aim of Cement and Concrete Research is to publish the best research on the materials science and engineering of cement, cement composites, mortars, concrete and other allied materials that incorporate cement or other mineral binders. In doing so, the journal will focus on reporting major results of research on the properties and performance of cementitious materials; novel experimental techniques; the latest analytical and modelling methods; the examination and the diagnosis of real cement and concrete structures; and the potential for improved materials. The fields which the journal aims to cover are: • Processing: CCement manufacture, admixtures, mixing, rheology and hydration. While the majority of articles will be concerned with Portland cements, we encourage articles on other mineral binders, such as alumino-silicates (often referred to as geopolymers), calcium aluminates, calcium sulfoaluminates, magnesia-based cements, as well as in a more limited way on lime and/or gypsum-based materials. • Chemical, microstructural and structural characterization of the unhydrated components and of hydrated systems including: the chemistry (structure, thermodynamics and kinetics), crystal structure, pore structure of cementitious materials, characterization techniques, and the modelling on atomistic, microstructural and structural levels. • The properties and modelling of cement and concrete, including: fundamental physical properties in both fluid and hardened state; transport, mechanical and other properties; the processes of degradation of cementitious materials; and the modelling of properties and degradation processes, as a means of predicting short-term and long-term performance, of relating a material's structure to its properties and of designing materials of improved performance, in particular with lower environmental impact. Papers dealing with corrosion will be considered provided their clearly relate to process fundamentally affected by the interplay between steel reactivity and a surrounding cementitious material. • Applications for cement, mortar and concrete keeping a clear focus on fundamental questions of materials science and engineering focus will be welcome on topics including: concrete technology, rheology control, fiber reinforcement, waste management, recycling, life cycle analysis, novel concretes and digital fabrication. The journal's principal publications are original articles containing new information, major reviews and selected papers from important conferences. Discussion of published material and rapid communications will form part of the journal where appropriate. The journal will focus on papers with a broad interest, based upon their subject area, the quality of the research, the novelty of the results and the potential for assimilation of the findings. Cement and Concrete Research is the companion title to the open access journal Cement.
