Special Issue Information

Dear Colleagues,

Cementitious material, including Portland cement concrete, polymer-cement-based composites, etc., have highly complex phase compositions. The increase in demand for high-performance cementitious material in recent years has resulted in renewed interest in the study of new technologies for investigating microstructures and enhancing the performance of cementitious materials. The development of advanced and effective experimental techniques over the last decade, such as X-ray diffraction (XRD), thermogravimetry analysis (TG), scanning electron microscopy (SEM), infrared spectroscopy (IR), air void analyzer, nanoindentation, mercury intrusion porosimetry (MIP), and nuclear magnetic resonance (NMR), has revealed that the micro-scale properties of materials have a significant effect on their macro-scale properties. However, traditional technologies have not been able to keep up with the increasing complexity of available cementitious materials. With the rise of increasingly advanced teaching and training in cementitious materials, the need has emerged for an up-to-date practical guide suitable for graduate students and junior and general practitioners in this field. This Special Issue will provide the cement scientific community with a state-of-the-art overview of the analytical techniques used in cement chemistry to study the hydration and microstructure of cements. A one-of-a-kind reference providing the do’s and don’ts of cement chemistry, this Special Issue will present the latest research and development of characterization techniques for cementitious materials, and serves as an invaluable resource for practicing professionals and those specializing in cement and concrete materials and other areas of cement and concrete technology.

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Materials is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2600 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

The constant current accelerated corrosion test was used to study the durability of magnesium oxychloride-coated reinforced concrete (MOCRC) in order to solve the problem of MOCRC’s durability. The relative dynamic elastic modulus was utilized as the failure threshold to evaluate the concrete durability, and the collected life data of concrete under different cover thickness were acquired. On the basis of the Gumbel distribution, the probability analysis can be used to study and foretell the life data. The results show that when the durability is evaluated by the relative mass and the relative dynamic modulus of elasticity, the durability of MOCRC with a larger protection layer thickness is better; the relative dynamic modulus of elasticity can better reflect the durability change in MOCRC than the relative mass. When the Gumbel distribution is used for durability analysis, the calculated value of the model and the life data have a relatively high degree of fit, which can provide a reference basis for the durability evaluation of concrete.
