Abstract | Geopolymer concrete has been receiving a great attention by the researchers due to the world wide focus on using more environmentally friendly products in the construction industry. There is no literature available on the effect that differing strain rates have on geopolymer concrete, a gap in the literature that this project aims to fill. The mix design used in this project achieved different compressive strengths by varying the heat curing time. In Australia, fibre reinforced geopolymer concrete is being used in precast panels in underground constructions. Commercially available geopolymer cement and synthetic fibres are effectively being used to produce elements that are more durable. A total of eight different batches were made by having two curing regimes (oven curing with different times and ambient curing) and two different polypropelene fibre concentrations (0.05% and 0.15% fibres by weight). All the samples were 100 mm diameter and 200 mm high, tested on the 28 day and the tests were duplicated. These were tested under three different strain rates, 0.5 mm/min, 1 mm/min and 2 mm/min. |
