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.

There is an increasing global recognition of the need for environmental sustainability in mitigating the adverse impacts of cement production. Despite the implementation of various carbon dioxide (CO2) mitigation strategies in the cement industry, such as waste heat recovery, the use of alternative raw materials and alternative fuels, energy efficiency improvements, and carbon capture and storage, overall emissions have still increased due to the higher production levels. The resolution of this matter can be efficiently achieved by the substitution of traditional materials with an alternative material, such as calcined clay (CC), construction and demolition waste (CDW), which have a significant impact on various areas of sustainable development, including environmental, economic, and social considerations. The primary objectives of employing CDW in the Portland cement production are twofold: firstly, to mitigate the release of CO2 into the atmosphere, as it is a significant contributor to environmental pollution and climate change; and secondly, to optimize the utilization of waste materials, thereby addressing the challenges associated with their disposal. The purpose of this work is to present a thorough examination of the existing body of literature pertaining to the partial replacement of traditional raw materials by CDW and the partial replacement of Portland cement by CDW and to analyze the resulting impact on CO2 emissions.
