Effect of Superplasticizer on the Properties of Kenaf Fibre-Reinforced Geopolymer Concrete
The use of fibres in concrete production has attracted a lot of interest because of the low tensile properties of concrete. Lately, extensive studies have been conducted on the incorporation of different types of natural fibres in geopolymer composites as an environmentally friendly alternative to steel and synthetic fibres. However, the incorporation of natural fibres has a negative impact on workability in terms of properties in the fresh state. Several studies showed that the addition of the superplasticizer (SP) is one of the solutions to overcome this issue. But the performance of geopolymer concrete with the inclusion of kenaf fibres and different SP content is not studied yet. In this paper, the fresh and mechanical properties of kenaf fibre-reinforced geopolymer concrete (KFRGC) with the addition of different SP contents i.e., 0, 1, and 2%, are studied. The workability of KFRGC was dependent on the percentage of the SP. With the increase in the dosage of the SP, the workability was enhanced. However, the addition of the SP in a high percentage decreased the strength performance of the concrete. The best results were achieved with the addition of 1% which improved the workability of KFRGC by about 67%. These findings demonstrate the positive impact of using the appropriate percentage of SP on the performance of KFRGC in the fresh state.
