Novel insulation material of glass bubble was used as a replacement of fly ash binder to significantly enhance the mechanical and thermal properties compared to the geopolymer paste. The results showed that the density and compressive strength of 50% glass bubble was 1.45 g/cm3 and 42.5 MPa, respectively, meeting the standard requirement for structural concrete. Meanwhile, the compatibility of 50% glass bubbles tested showed that the thermal conductivity (0.898 W/mK), specific heat (2.141 MJ/m3K), and thermal diffusivity (0.572 mm2/s) in meeting the same requirement. The improvement of thermal insulation properties revealed the potential use of glass bubbles as an insulation material in construction material.}, type={Article}, title={Thermal Insulation and Mechanical Properties in the Presence of Glas Bubble in Fly Ash Geopolymer Paste}, URL={http://www.czasopisma.pan.pl/Content/122527/PDF-MASTER/AMM-2022-1-28-Al%20Bakri%20Abdullah.pdf}, doi={10.24425/amm.2022.137493}, keywords={glass bubble, thermal insulation, geopolymers, fly ash}, }
