Manuscripts in most areas of science are welcomed except in areas such as agriculture, engineering and medical science which are outside the scope of the Journal. Currently, we focus on manuscripts in biology, chemistry, physics, materials science and environmental science. Papers in mathematics statistics and computer science are also included but should be of an applied nature rather than purely theoretical. Manuscripts describing experiments on humans or animals are required to provide proof that all experiments have been carried out according to the ethical regulations of the respective institutional and/or governmental authorities and this should be clearly stated in the manuscript itself. The Editor reserves the right to reject manuscripts that fail to do so. In this study, the geopolymer materials were prepared by geopolymerization process, using calcined diatomite (from Lampang province) and metakaolin (from Ranong province) with alkali activators (NaOH and Na2SiO3 solutions). The fresh slurry was casted in a plastic mold with cubic shape and cured at room temperature. Effects of calcination temperature of diatomite were investigated. Material characterizations, including XRD, XRF, and SEM, were used in this work. The maximum density of the geopolymer samples was 1.43 g/cm3, observed for the sample containing diatomite which calcined at 700 C. To determine the mechanical property (compressive strength), the geopolymers were tested after the curing process (for 28 days). The result suggested that the compressive strength of the samples can be linked with the porosity of the samples, where the sample contained diatomite which calcined at 700 C had the highest compressive strength of 18.90 MPa. 2020-10-08T08:36:16Z 2020-10-08T08:36:16Z 2020 Chiang Mai Journal of Science 47,4 (Special Issue II : July 2020), p.786-795 2465-3845 https://epg.science.cmu.ac.th/ejournal/dl.php?journal_id=11106 http://cmuir.cmu.ac.th/jspui/handle/6653943832/69891 Eng Faculty of Science, Chiang Mai University
