Abstract

In this research paper, an attempt has been made to develop the geopolymer lightweight concrete using the industrial by-products such as fly ash class-C, GGBFS, PS sand and sintered fly ash aggregates to achieve the required workability and strength. The use of fly ash and GGBFS in different ratios as binder material were studied in this work. The geopolymer lightweight concrete was developed at ambient curing. The liquid – binder ratio was maintained at 0.4 for all the mix under study. The workability of concrete was measured with help of slump cone test, compaction factor test and flow test using inverted slump cone. The workability test results indicate the present geopolymer concrete under study can be termed as self-compacting and self-levelling concrete. The density of this concrete was in the range of 1740Kg/m3 to 1840Kg/m3. The higher the GGBFS content better is the workability and density. The compressive and flexural strength developed in geopolymer concrete after 28 days of curing is in the range of 27 Mpa to 43 Mpa and 5 Mpa to 8 Mpa respectively. Hence this Lightweight Geopolymer concrete can be produced with required workability and strength. This green concrete utilization in large scale can reduce the cost of the building.
