Special Issue Information

Dear Colleagues,

It is a well-known fact that the construction sector, in its broadest sense, is one of the major causes of human environmental impact on the earth. More than one-third of the energy consumed, CO2 emissions into the atmosphere, and solid waste in the EU are due to the activity of this sector. Cement is the most widely used material in this sector and, at the same time, the cement industry is the largest source of CO2 emissions in the entire industry, emitting around 800 kg of CO2 per tonne of cement produced. It is, therefore, an urgent need to decarbonize this activity.

Although most of the environmental impact in this sector occurs during the useful life of the edifice, a significant portion also occurs during the construction and deconstruction of the building. This is where the choice of sustainable and high-performance materials can be a key to reducing the footprint of this activity on the planet. On the other hand, materials composed of a mineral matrix reinforced with sustainable fibers are a very versatile product that can play multiple roles in the building, from pavements, coatings, and roofing plates, to elements for interior partitions. They can also play a very important role in elements of urban implementation, from different types of surface treatments to street furniture. We can also add that it is an affordable product and can provide solutions for housing needs in developing countries or in social housing developments in large cities.

In this Special Issue we aim to provide the latest developments in research on sustainable composite materials of the mineral matrix (and, therefore, gypsum, lime, cement of all kinds, geopolymers, etc.), reinforced with any type of fiber. We want to know and collect a representative sample of the materials being developed in the laboratory as a sustainable alternative to existing products on the market, which could be replaced due to their good outputs.

Manuscript Submission Information

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.

Bentonite cement paste (BCP) is among the grouting materials used widely in large-pore grouting and karst cave treatment. The mechanical properties of bentonite cement paste (BCP) will be improved by additional basalt fibers (BF). In this study, the effects of basalt fiber (BF) contents and their lengths on the rheological and mechanical properties of bentonite cement paste (BCP) have been examined. Yield stress (YS), plastic viscosity (PV), unconfined compressive strength (UCS), and splitting tensile strength (STS) were used to evaluate the rheological and mechanical properties of basalt fiber-reinforced bentonite cement paste (BFBCP). Scanning electron microscopy (SEM) and energy-dispersive x-ray spectroscopy (EDS) characterize microstructure development. The results indicate that the Bingham model can provide the rheological behavior of basalt fibers and bentonite cement paste (BFBCP). The yield stress (YS) and plastic viscosity (PV) increase as the content and length of basalt fiber (BF) increase. The effect of fiber content on yield stress (YS) and plastic viscosity (PV) is greater than that of fiber length. The addition of basalt fiber (BF) enhanced the unconfined compressive strength (UCS) and splitting tensile strength (STS) of basalt fiber-reinforced bentonite cement paste (BFBCP) at the optimum basalt fiber (BF) content of 0.6%. The optimum basalt fiber (BF) content tends to increase as curing age increases. The basalt fiber length of 9 mm is the most effective for improving unconfined compressive strength (UCS) and splitting tensile strength (STS). The large increments in unconfined compressive strength (UCS) and splitting tensile strength (STS) were 19.17% and 28.21% for the basalt fiber-reinforced bentonite cement paste (BFBCP), with a basalt fiber length of 9 mm and content of 0.6%. Scanning electron microscopy (SEM) shows that the randomly distributed basalt fiber (BF) forms a spatial network structure in basalt fiber-reinforced bentonite cement paste (BFBCP), which composes a stress system under the action of cementation. Basalt fibers (BF) used in crack generation processes slow down the flow through bridging and occur in the substrate to improve the mechanical properties of basalt fiber-reinforced bentonite cement paste (BFBCP).
