Starting from the context of the principles of Sustainable Development and Circular Economy concepts, the paper presents a synthesis of research in the field of the development of materials of interest, such as cementitious composites or alkali-activated geopolymers. Based on the reviewed literature, the influence of compositional or technological factors on the physical-mechanical performance, self-healing capacity and biocidal capacity obtained was analyzed. The inclusion of TiO nanoparticles in the matrix increase the performances of cementitious composites, producing a self-cleaning capacity and an anti-microbial biocidal mechanism. As an alternative, the self-cleaning capacity can be achieved through geopolymerization, which provides a similar biocidal mechanism. The results of the research carried out indicate the real and growing interest for the development of these materials but also the existence of some elements still controversial or insufficiently analyzed, therefore concluding the need for further research in these areas. The scientific contribution of this study consists of bringing together two apparently distinct research directions in order to identify convergent points, to create a favorable framework for the development of an area of research little addressed so far, namely, the development of innovative building materials by combining improved performance with the possibility of reducing environmental impact, awareness and implementation of the concept of a Circular Economy.
本文从可持续发展原则和循环经济概念的背景出发,对水泥基复合材料或碱激活地质聚合物等相关材料开发领域的研究进行了综述。基于所查阅的文献,分析了成分或工艺因素对所得材料物理力学性能、自愈能力和杀菌能力的影响。在基体中加入二氧化钛纳米颗粒可提高水泥基复合材料的性能,产生自清洁能力和抗菌杀菌机制。作为一种替代方法,可通过地质聚合实现自清洁能力,其具有类似的杀菌机制。所开展的研究结果表明,人们对这些材料的开发确实有着浓厚且不断增长的兴趣,但同时也存在一些仍有争议或分析不足的因素,因此得出在这些领域需要进一步研究的结论。本研究的科学贡献在于将两个明显不同的研究方向结合起来,以找出交汇点,为一个迄今很少涉及的研究领域的发展创造有利框架,即通过将性能提升与减少环境影响的可能性相结合、提高对循环经济概念的认识并加以实施,来开发创新型建筑材料。
