Mohd Ramli Burduhos-Nergis, D. D. Rafiza, Abd Razak zarinayahya@unimap.edu.my Center of Excellence Geopolymer and Green Technology (CEGeoGTech), School of Materials Engineering, Universiti Malaysia Perlis (UniMAP) Department of Civil Engineering Technology, Faculty of Engineering Technology, Universiti Malaysia Perlis (UniMAP) Faculty of Materials Science and Engineering, Gheorghe Asachi Technical University of Iasi Geopolymer concrete Kaolin Geopolymers Link to publisher's homepage at https://iopscience.iop.org/ Development of geopolymer concrete is mainly to reduce the production of ordinary Portland cement (OPC) that adverse the natural effect. Fly ash is a by-product collected from electrical generating power plant which resulted from burning pulverized coal. Since fly ash is waste materials, it can be recycled for future advantages particularly as pozzolanic materials in construction industry. This study focused on the feasibility of fly ash based geopolymer concrete to which kaolin has been added. The main constituents of geopolymer production for this study were class F fly ash, sodium silicate and sodium hydroxide (NaOH) solution. The concentration of NaOH solution was fixed at 12 Molar, ratio of fly ash/alkaline activator and sodium silicate/NaOH fixed at 1.5 and 2.5, respectively. Kaolin was added in range 5% to 15% from the mass of fly ash and all the samples were cured at room temperature. Destructive and non-destructive test were performed on geopolymer concrete to evaluate the best mix proportions that yield the highest strength as well as the quality of the concrete. Compressive strength, flexural strength, rebound hammer and ultrasonic pulse velocity (UPV) result have been obtained. It shown that 5% replacement of kaolin contributed to maximum compressive strength and flexural strength of 40.4 MPa and 12.35 MPa at 28 days. These result was supported by non-destructive test for the same mix proportion. 2022 2022-03-10T08:44:57Z 2022-03-10T08:44:57Z 2018-06 Article IOP Conference Services: Material Sciences Engineering, vol.374, 2018, 11 pages 1757-899x (online) http://dspace.unimap.edu.my:80/xmlui/handle/123456789/74621 https://doi.org/10.1088/1757-899x/374/1/012068 en IOP Publishing Ltd |
