“…In the last decades, TiO 2 nanoparticles have been employed as additive agents in concretes, paints, tiles and antifogging coatings, also showing photocatalytic properties for the protection from UV light degradation [ 103 ]. In a paper reported by Maiti et al, the integration of TiO 2 nanoparticles of 30 nm in a fly ash-based geopolymeric matrix led to a more compact and densified formulation with a decrease of the porosity and the roughness of the structure, thus enhancing mechanical properties [ 98 ].…”

In the last decades, new synthetic hybrid materials, with an inorganic and organic nature, have been developed to promote their application as protective coatings and/or structural consolidants for several substrates in the construction industry and cultural heritage field. In this context, the scientific community paid attention to geopolymers and their new hybrid functional derivatives to design and develop innovative and sustainable composites with better chemical resistance, durability and mechanical characteristics. This review offers an overview of the latest progress in geopolymer-based hybrid nanofunctional materials and their use to treat and restore cultural heritage, as well as their employment in the building and architectural engineering field. In addition, it discusses the influence of some parameters, such as the chemical and physical characteristics of the substrates, the dosage of the alkaline activator, and the curing treatment, which affect their synthesis and performance.

“…9 In recent years, the combination of photocatalysts (especially nano-TiO 2 ) and cementitious materials has been widely investigated. 10,11 On the one hand, the strong bonding qualities of cementitious materials make it easier for photocatalysts to remain immobilized throughout practical use. 12,13 On the other hand, the calcium carbonate in cement mortars might react with the nitric acid coming from the end product of NO photooxidation, yielding calcium nitrates that could be readily removed from the surface of the photocatalyst.…”

“…An essential condition in overcoming these complex issues is developing new building materials that have high strength and durability and, at the same time, are safe for human health and for the natural environment. The application of nanotechnologies in construction enables the design and modification of material structures so that we receive a product with the expected strength and some special directional properties, such as resistance to external physical and chemical factors, as well as being self-cleaning, antibacterial or self-repairing [ 3 , 4 , 5 , 6 , 7 , 8 , 9 , 10 , 11 ]. The EU lists this area of research in the document called “Roadmap 2014” as a key one.…”

This paper presents an analysis of research results for silica aerogel cement composites over the past twenty years. Recently, two trends in the development of these composites have been noted, towards structural applications and towards ultralight composites for coatings and renders. Ongoing research shows that important aspects of cementitious composites with good mechanical performance are the proper selection of aggregates and improved adhesion at the silica aerogel–cement binder interface, which will guarantee high compressive strength with the lowest possible thermal conductivity. The best physicomechanical performance of aerogel cement composites with low thermal conductivity below 0.03 W/(m·K) was obtained when cenospheres and aerogel were used in a weight percentage of 5%. In turn, the prerequisites for using aerogel cement composites as coatings for energy-efficient building façades are the use of large amounts of silica aerogel as a substitute for lightweight aggregates or the selection of an optimal composition of lightweight aggregates and aerogel, ensuring the lowest possible thermal conductivity coefficient. Other important standpoints are water transport and moisture protection of the silica aerogel-based coatings. Therefore, in recent years, more and more elements of the hygrothermal performance, porosity and durability of silica aerogel cement composites have been developed. The article also points out the weaknesses of the application of silica aerogel in the cement matrix, the most important of which are the lack of adhesion at the boundary of the aerogel–cement binder, the increased porosity of the composite, the high water absorption capacity and the significant decrease in compressive strength with large volumes of silica aerogel. Solving these issues will certainly contribute to the wider applicability of these materials in the construction industry.
