“…The study of aerogel (Garrido et al, 2019) and aerogel-based renders is increasing due to their excellent thermal performance and application on thermal rehabilitation of walls, with decreased thicknesses solutions when compared with other conventional thermal renders. In the literature there are already a few number of studies that focus on in-situ testing of aerogel-based renders, but mainly on the hygrothermal behavior of these renders based on numerical simulations (Fantucci et al, 2020;Fenoglio et al, 2018;Ibrahim et al, 2014;Stahl et al, 2017).…”

In this paper, two aerogel-based renders are characterized based on in-situ testing of walls prototypes. The in-situ tests to assess the mechanical performance are: pull-off, surface impact tests and compressive strength on collected samples. The physical performance includes the water resistance and thermal conductivity coefficient. The tests carried out to assess water-resistance are: Karsten tube, moisture meter and capillary water absorption of collected samples. The thermal performance was tested based on infrared thermography and thermal conductivity transient method. The combination of these in-situ tests allowed a better performance characterization of the aerogelbased renders and characterized the applied renders. These results were carried out under two national research projects (Nanorender and P2020 PEP).

“…The remaining 13% is made up from natural products, such as cork [41], hemp shive [42], palm date fibers [43], wood wool [44], flax and straw rape [45], etc. Also, inorganic expanded materials, such as perlite and expanded glass have found use in composition of thermal insulation mortars [46,47]. Incorporation of innovative high thermal insulating aggregates, e.g., aerogels, has also been studied but their presence on the market is still at a low level [48,49,50].…”

Mortars with Crushed Lava Granulate for Repair of Damp Historical Buildings

et al. 2019

In this paper, crushed lava granulate was used as full silica sand replacement in composition of repair mortars based on hydrated lime, natural hydraulic lime, or cement-lime binder. Lava granules were analyzed by X-ray fluorescence analysis (XRF), X-ray diffraction (XRD), and scanning electron microscopy (SEM). Particle size distribution of both silica and lava aggregates was assessed using standard sieve analysis. Hygrothermal function of the developed lightweight materials was characterized by the measurement of complete set of hygric, thermal, and structural parameters of the hardened mortar samples that were tested for both 28 days and 90 days cured specimens. As the repair mortars must also meet requirements on mechanical performance, their compressive strength, flexural strength, and dynamic Young’s modulus were tested. The newly developed mortars composed of lava aggregate and hydrated lime or natural hydraulic lime met technical, functional, compatibility, and performance criteria on masonry and rendering materials, and were found well applicable for repair of historically valuable buildings.

Thermal insulating plasters and renders are becoming a popular solution for the energy retrofit of existing and historic buildings because of their suitability/compatibility with the existing masonry supports. However, as for most of the insulating products, the actual performance of these materials might significantly differ from the one determined with simplified methods (EN ISO 6946 standard) that are commonly adopted by the designers. In this study, an overview of the latest Authors researches that involve three different thermal insulating plasters, containing respectively perlite, vegetal and aerogel aggregates, are presented. The developed plasters were characterized in the laboratory and successively applied in three demonstration buildings. From the in-field thermal monitoring activities, all the analysed thermal insulating plasters showed a decrease in the thermal performance between 25 and 30% if compared to the laboratory measurements.
