| Summary: | In this study of various percentage addition of glass bubble as thermal insulated material (2.5, 5.0, 7.5 and 10
%) has influenced the concrete performance such as density, compressive strength and thermal conductivity. The
compressive strength of geopolymer concretes achieved the maximum strength with 10 % glass bubble at 65.25 MPa for
90 days with the lowest density achieved at 2165 kg/m³. The thermal conductivity of geopolymer concrete with the
present addition of glass bubble as thermal insulated materials showing better thermal insulation properties with decrease
of density to 1.20 W/mK. Results highlight the thermal conductivity showing better result with reducing density of the
geopolymer concrete due to the addition of glass bubble in the geopolymer concrete. The unique of spherically shape and
light hollow sphere of glass bubble in the geopolymer concrete contributed better performance towards thermal insulation
application with low density and thermal conductivity within applicable strength. |
