Mechanical Properties of Volcanic Ash Based Geopolymer Concrete

Abstract:

This paper presents the result of study on using volcanic ash which obtained from Mount Kelud as fly ash replacement material to produce geopolymer concrete. Test was conducted on geopolymer concrete mixture with 0%, 25%, 50% and 100% fly ash replacement with Kelud volcanic ash. Sodium hydroxide (NaOH) and Sodium Silicate (Na₂SiO₃) were applied as alkaline activator. The mechanical properties was assessed by compressive strength while workability of fresh concrete by slump test. Producing geopolymer concrete with volcanic ash is possible with maximum replacement of up to 50%. Research and development on eco-friendly material such as volcanic ash is very useful to help reconstruction process of volcanic disaster around the world.
