Abstract
The construction industry is increasingly turning to the use of environmentally friendly materials in order to meet the sustainable aspect required by modern infrastructures. Geopolymer is an emerging alternative binder for concrete that uses materials that are normally considered and waste or by products of low value. In geopolymerization, a material that is rich in Silicon (Si) and Aluminium (Al) reacts in an alkaline solution (medium) to produce the binder. Materials such as Fly ash, Metakaolin, slimes, and Palm fuel ash can are used to make Geopolymer concrete. Slag based Geopolymer concrete has advantages like faster strength gain, ambient curing, low concentration of KOH and so on. Here Palm fuel ash based Geopolymer has been developed and highlighted. It is generally seen that addition of palm fuel ash results in an increased viscosity of the mix, the mix tends to be stickier in nature, demanding a higher water content or workability aiding admixtures. Incorporation of palm fuel ash tends to marginally increase the strength developed and also better durability performance. This paper present results of an experimental study on the flexural, tensile and compressive strength of Geopolymer concrete. The experiments were conducted on palm fuel ash based Geopolymer concrete by varying the types of curing namely ambient curing and hot curing. In the present study, 8M on potassium hydroxide are to be used as well as potassium silicates are to be used based on the quantity of concrete.
