Special Issue Information

Dear Colleagues,

The discovery and exploitation of materials has greatly influenced our advancement as a civilization and enabled great improvements in our quality of life. This is especially true in the case of the materials of modern construction, viz. cement, concrete, and steel, which have led to the emplacement of buildings and infrastructure which fulfill functions ranging from human habitation structures, to sanitation and water conveyance systems and infrastructure. While, unarguably, cement, concrete (i.e., a mixture of cement, sand, stone, and water), and steel have found extensive use in the construction of building and infrastructure—e.g., in the construction of framed steel and reinforced concrete structures—the environmental impact of these materials poses foundational challenges. For example, at the current level of production—around 4.2 B tons in 2018—cement alone is responsible for nearly 9% of global CO2 emissions. This number is only expected to grow as development-related construction in Asia and Africa further expands the scale of cement production. This is an issue not only for the obvious impacts on climate change, but also because the imposition of CO2 penalties is expected to, in time, double the price of cement. The implications of this are straightforward, i.e., materials engineers working in the civil engineering field need to:

  • Identify alternate materials: Identify compositionally optimal, low-CO2 materials which can be used to replace and thereby reduce the use of cement as the binder in concrete or propose novel, functionally effective, and environmentally friendly construction materials;
  • Extend the service-life of infrastructure: Develop functional pathways to mitigate steel corrosion, which is unarguably the leading cause of premature structural decay of infrastructure.

Taking all of the above into consideration, this Special Issue aims to highlight recent findings and provide useful guidelines or problem solution options to consider for scientists and engineers dealing with sustainability and durability of the construction materials.

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 papers will be 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.

The purpose of this study was to evaluate the effects of sintering temperature and sintering time on mineral composition of high-alite white Portland cement clinker and hydration activity of the clinker. Effects of sintering temperature and sintering time on clinker mineral composition, C3S polymorph and size and hydration heat release rate were analyzed by X-ray diffraction (XRD), scanning electron microscope (SEM), differential scanning calorimetry&Thermogravimetric Analysis (DSC-TG) and isothermal heat-conduction calorimetry. Results shown that, with the increase of sintering temperature (1450–1525 °C) and sintering time (60–240 min), free lime (f-CaO) in clinker decreased, C3S grain size increased, and C3S crystal type changed from T3 to M type and R type, which exhibits higher symmetry. The hydration activity of different C3S crystals ranged from high to low as follows: T3→M1→M3→[email protected] Full article
