Article Synopsis
- The paper explores the principles of Sustainable Development and Circular Economy while focusing on the development of materials like cementitious composites and alkali-activated geopolymers.
- It analyzes how different compositional and technological factors impact the physical-mechanical properties, self-healing abilities, and biocidal properties of these materials, particularly enhanced by the addition of TiO nanoparticles.
- The study highlights the increasing interest in these innovative materials but also points out the need for further research to address controversial aspects and promote the integration of improved performance with reduced environmental impacts in building materials.
The use of waste from industrial activities is of particular importance for environmental protection. Fly ash has a high potential in the production of construction materials. In the present study, the use of fly ash in the production of geopolymer paste and the effect of FeO, MgO and molarity of NaOH solution on the mechanical strength of geopolymer paste are presented.

Once the concrete has dried, the crystalline chemicals sit dormant until another dose of water starts the crystallization again. The research aims to analyses the early age self-sealing effect of a crystalline admixture at a dosage rate of 1-3% of the cement mass.
