The objective of this research is to compare the performance of geopolymer concrete (GPC) with ordinary Portland cement (OPC) concrete infilled lightweight expanded clay aggregate (LECA) in seawater exposure. Geopolymer concrete is produced by using alkaline activator to activate the raw material, FA. The highest compressive strength of this study is 42.0 MPa at 28 days and 49.8 MPa at 60 days. The density for this concrete is in the range of 1580 kg/m³ to 1660 kg/m³. The result for water absorption is in the range of 6.82% to 14.72%. However, the test results of weight loss is in the range between 0.30% to 0.43%. 2022 2022-03-10T02:27:13Z 2022-03-10T02:27:13Z 2017-11 Article IOP Conference Services: Material Sciences Engineering, vol.209, 2017, 7 pages 1757-899x (online) http://dspace.unimap.edu.my:80/xmlui/handle/123456789/74607 https://doi.org/10.1088/1757-899x/267/1/012012 en International Conference on Innovative Research (ICIR Euroinvent 2017); IOP Publishing Ltd |
