This research identified the possibility of application as an insulation building material by mixing aerogels with the cement paste as well as their thermal performance. The aerogel is a very stable material against water because of their skeleton’s characteristics, so that re-treatment of aerogel had to be preceded before mixing with cement pastes. Chemical and physical stability caused by the re-treatment of aerogel in the cured cement were confirmed by Fourier transform infrared spectroscopy (FT-IR) and scanning electron microscope (SEM). Moreover, thermal conductivity of aerogel cement was 0.135 W/m K which is 75% of aerogel-free cement’s thermal conductivity, 0.533 W/m K.
This paper highlights application of the MTPS method of C-Therm's Trident Thermal Conductivity Analyzer.
