In this research, lightweight aggregate geopolymer concretes was incorporated with different percentage of foaming agents (hydrogen peroxide). Compressive strength and thermal conductivity were measured. From results obtained, increased H₂O₂ contents will decrease the strength of lightweight foamed geopolymer concretes. Lightweight aggregate foamed geopolymer concretes (LWAFGC) with foaming agent content of 0.2wt.% obtained the highest strength of 19.601 MPa. Furthermore, Increased of H₂O₂ contents also will decrease the thermal conductivity of lightweight foamed geopolymer concretes. Lightweight foamed geopolymer concretes with 2wt.% H₂O₂ gave the good thermal insulating behavior when the thermal conductivity value recorded the lowest value compare to other wt.% of H₂O₂ content. The thermal conductivity value of lightweight foamed geopolymer concretes with 2wt.% of H₂O₂ was 0.072 W/m. K while, the thermal conductivity of other mixtures ranged between 0.077 W/m. K to 0.087 W/m. K., respectively. 2022 2022-03-15T01:14:30Z 2022-03-15T01:14:30Z 2019-08 Article IOP Conference Services: Material Sciences Engineering, vol.551, 2019, 7 pages 1757-899x (online) http://dspace.unimap.edu.my:80/xmlui/handle/123456789/74638 https://doi.org/10.1088/1757-899x/551/1/012089 en IOP Publishing Ltd |
