Special Issue Information
Dear Colleagues,
Concrete is a composite material of fine and coarse aggregate bonded with a fluid cement (cement paste) that hardens (cures) over time. Concrete is the second most used substance in the world after water and is the most widely used building material. Its usage worldwide, ton for ton, is twice that of steel, wood, plastics, and aluminum combined. Globally, the ready-mix concrete industry, the largest concrete market segment, is projected to exceed USD 600 billion in revenue by 2025. This widespread use results in several environmental impacts. Most notably, the production process for cement produces large volumes of greenhouse gas emissions, leading to a net 8% of global emissions. Other environmental concerns include widespread illegal sand mining, impacts on the surrounding environment such as increased surface runoff or urban heat island effect, and potential public health implications from toxic ingredients.
Electrical resistivity (ER) is an important criterion for evaluating cement-based materials and structural health monitoring, such as concrete, since it allows the material to respond to strain or cracks. ER is a characteristic of concrete that reflects the degree of difficulty with which ions may move. ER may be utilized to measure corrosion and durability and monitor the status of standard samples over time. Because the approach is non-destructively tested, it was perfect for on-site quality control. Including steel creation slag decreased the ER of concrete while increasing the quantity of steel production slag in the mix enhanced conductivity. According to published data, the electrical resistivity measurements range from extremely low to very high values. This is because a measurement technique, device measurement, and low frequency cause a high electrical resistivity value. The frequency range utilized was 0.5–1 kHz, and the literature used two electrical measuring methods: two probes and four probes.
Therefore, this Special Issue in Sustainability is dedicated to comprehensive reviews and original studies on resource use (e.g., nondestructive tests, piezoelectrical resistivity, and green synthetic nano conductive materials) of cementitious materials and concrete containing less common, non-conventional materials.
We look forward to receiving your contributions.

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. Sustainability 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 2400 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.
