Conventional hot-air and microwave heating alternatives were tested singly and in combinations, with microwave heating as first or last in the combination. The GM-NRL properties observed were thermal, dielectric, and mechanical properties. The tested NRL addition levels were 5, 8, and 10% by weight of lignite fly ash. It was found that as the amount of NRL was increased, also water demand and hardening time of the geopolymer increased. Thermal conductivity (K) and specific heat (Cp) depended on the density of a cured specimen. NRL level of 10% by weight caused sharp drops in K and Cp. The NRL addition tended to increase dielectric characteristics while decreasing compressive strength. However, microwave curing gave superior compressive strength over the other curing methods tested. 2020-06-10T07:12:28Z 2020-06-10T07:12:28Z 2020 Chiang Mai Journal of Science 47,3 (May 2020), p.567-579 2465-3845 https://epg.science.cmu.ac.th/ejournal/dl.php?journal_id=10925 http://cmuir.cmu.ac.th/jspui/handle/6653943832/68749 Eng Faculty of Science, Chiang Mai University |
