“…Silica fume is an essential ingredient of UHPC which increases packing due to their nano size nature, but also further enhance the bond between the cement paste and aggregate particles through their hydration reaction with cements [88]. Further information concerning miscellaneous aerogel investigations, also including aerogel windows, may be found in the available literature [89][90][91][92][93][94][95][96][97][98][99][100][101][102].…”

“…In the recent years, researchers have also been trying to investigate some other materials like cenosphere (Chávez-Valdez et al 2011;Kwan and Chen 2013;Pichór 2009;Wang et al 2012Wang et al , 2013Wu et al 2015;Xu et al 2015) and aerogel particles (Gao et al 2014;Hanif et al 2016;Kim et al 2013;Ng et al 2015) for their use as LWF. Xu et al found that even though incorporating cenosphere in magnesium oxy-chloride cement composite reduces the compressive strength, still high levels of strength (60 MPa) are achieved (Xu et al 2015).…”

Abstract:The effects of different lightweight functional fillers on the properties of cement-based composites are investigated in this study. The fillers include fly ash cenospheres (FACs) and glass micro-spheres (GMS15 and GMS38) in various proportions. The developed composites were tested for compressive, flexural and tensile strengths at 10 and 28-day ages. The results indicated that both FACs and GMS38 are excellent candidates for producing strong lightweight composites. However, incorporation of GMS15 resulted in much lower specific strength values (only up to 13.64 kPa/kg m 3 ) due to its thinner shell thickness and lower isostatic crushing strength value (2.07 MPa). Microstructural analyses further revealed that GMS38 and GMS15 were better suited for thermal insulating applications. However, higher weight fraction of the fillers in composites leads to increased porosity which might be detrimental to their strength development.

“…The continuous challenge to increase the thermal performance of insulation materials for building applications has resulted in the emergence of a variety of new SiO 2 aerogel containing materials such as aerogel plasters , aerogel containing insulations , lightweight concrete , cement and glazing systems in the construction market. There are also running EU projects dealing with aerogel containing materials to be used for reduction in energy consumption of buildings .…”

Aerogel containing ceramic fibre insulations represent a newly developed high performance insulation material applied in industrial installations and recently expanding rapidly into the construction industry to reduce the heat transfer through walls and ceilings. As a rather expensive material they are preferentially used in cases where slim layers of insulation are needed mainly in refurbishing of existing buildings especially those under heritage protection. The reaction to elevated temperatures in case of fire is a decisive property for building applications. The present article investigates the reaction to fire of an aerogel containing ceramic fibre insulation already available on the market. This reaction was monitored experimentally by means of temperature sensors at different depth in the material when subjected to the standard ISO fire. The measured temperature evolutions are discussed with respect to radiative heat transfer in an optically thick medium, temperature induced changes in density because of mass loss and the occurrence of endothermic and exothermic reactions detected by thermal analysis and compared with simulation results.

Each of the full lines represents the average of four thermocouples placed in the same depth, and the vertical bars are the corresponding standard deviations.
