Effect of Addition of Fly Ash and Superplasticizer on Ultra-fine Slag Based Geopolymer Mortar
Abstract Geopolymer is a promising sustainable supplementary cementitious material in construction industry. Researchers have found it to have strong potential for replacing the Portland cement in mortar and concrete. The present study reports experimental works performed on geopolymer mortar prepared from ultra-fine ground granulated blast furnace slag. Geopolymer mixes were prepared with alkali activator composed of sodium hydroxide solution and addition of certain admixtures such as fly ash and superplasticizer. The mixes were tested to study properties such as setting time, workability and strength. Addition of fly ash to slag based geopolymer was advantageous in terms of setting time and workability performance. However, very high amount of fly ash in the mix caused significant reduction in strength. Superplasticizer also modified the properties of geopolymer mixes at fresh and hardened state. High dosage of superplasticizer caused deterioration of performance of geopolymer mix.
