Special Issue Information

Dear Colleagues,

We would like to invite you to contribute to a Special Issue of the open access journal Applied Sciences dedicated to the “Effects of Temperature and Humidity on Cement Materials”.

Such materials include common products as concrete, mortar, grout, and terrazzo, soil-cement, and roller-compacted concrete—"cousins" of concrete, geopolymer, etc. The quickly developing way of life has increased the need for new cement-based materials and technologies in a broader market. Simultaneously, the current demands on environmental protection, energy saving, and sustainability have set the life cycles elongation of such products as the most crucial parameter among others.

Cement-based materials constantly interact with the environment, so influences such as temperature and humidity affect their moisture content, leading to significant undesirable phenomena such as pH increase or microbial growth, finally resulting in the deterioration of their strength. Therefore, intensive research on the effects of temperature and humidity on cement materials need to continue in the future in order to fully understand the effects and mechanisms that take place in order to develop improved resistant materials in time and under different conditions. 

Articles of interest for this Special Issue include, but are not limited to, the following topics: cement-construction materials and their resistance against various climate conditions (including T and humidity), concrete or other cementitious materials conservation against extreme conditions (climate or others), and the development of different cementitious materials and geopolymers with different additives for improved durability in time and exposure. 

We encourage authors to contribute their high-impact original research and review papers that include discussions of aspects related to the humidity and temperature parameters along with the microstructural characteristics and phase compositions of cement-based materials as well as with their physicochemical and other specific properties, since such studies contribute strongly to the understanding and explanation of the involved deteriorated mechanisms.

Due to its ability to improve mechanical properties when incorporated into cement, graphene oxide (GO) has received extensive attention from scholars. Graphene oxide is also a filler that improves the self-sensing properties of cement composites (CCs). However, existing studies have not focused sufficient attention on the electric conductivity of cement composites filled with graphene oxide (GO/CCs) and their mechanisms, especially polarization. This study examines the effects of water content and temperature on the electrical conductivity of GO/CCs. GO/CC polarization phenomena are analyzed to reveal the conductive mechanism. The results show that water has a significant influence on the electrical conductivity of GO/CCs. With increasing water loss, the electrical resistivity of GO/CCs increases by four orders of magnitude. For the same water content, a 0.1% GO concentration significantly decreases the resistivity of GO/CCs. Temperature can significantly enhance the current intensity of GO/CCs; furthermore, there is a quadratic relationship between current intensity and temperature. The conductive mechanism of GO/CCs is attributed to the interaction between ionic conductivity and electronic conductivity. Full article
