Special Issue Information

Dear Colleagues,

The construction industry has a notable impact on the environment and people's quality of life, contributing considerably to CO2 emissions, natural resource depletion and energy demand. The construction sector now tends to use alternative construction materials replacing natural resources, thus decreasing environmental impact and increasing sustainability.

This Special Issue aims to compile recent scientific advances in the use of secondary raw materials in new cementitious matrices and eco-efficient concretes. In particular, this Special Issue may cover experimental studies on the design of new cement-based materials and their applications in the intelligent construction of buildings and infrastructures to reduce their carbon footprint. This may also include studies on pre-treatments that enhance the improvement of these by-products, synergies between new cementitious materials, properties at nano, micro and macro levels that occur in concrete as a consequence of a change in the cement components and the type of aggregate.

Although this field of research is constantly growing, innovative studies with the application of 3D printing and also artificial intelligence in the field of construction with concretes incorporating this new typology of materials are particularly welcome.

We hope that this Special Issue will become a source of new ideas on the various advances in this field of research.

This study investigates the potential of bioaugmentation with Bacillus species to enhance wastewater treatment and develop a bacterial–CaCO3 system for self-healing cement applications. Utilizing microbiologically induced calcium carbonate precipitation (MICP), this study evaluates the dual functionality of Bacillus licheniformis and B. muralis strains. For wastewater treatment, the bioaugmentation process achieved significant pollutant reductions, including a 99.52% decrease in biochemical oxygen demand (BOD5), a 92.13% reduction in chemical oxygen demand (COD), and a substantial removal of heavy metals and nutrients. This process also produced high concentrations of CaCO3 precipitate enriched with viable bacterial cells, demonstrating an eco-friendly approach to improving water quality. For self-healing cement applications, bioaugmented CaCO3 crystals were coated with nutrient and sodium silicate layers to form a bacterial–CaCO3 coupled system. This system demonstrated a 92% recovery in compressive strength after 180 days, highlighting its ability to autonomously repair microcracks in cement-based materials. The layered encapsulation strategy ensured bacterial viability and a controlled activation mechanism, offering a scalable and sustainable solution for infrastructure resilience. This dual-function approach addresses critical environmental and construction challenges by linking efficient wastewater treatment with innovative self-healing material development, contributing to global sustainability and circular economy goals.
