Fly ASH Aggregates on Strength and Workability Characters of Geo-Polymer Concrete

Abstract

The Present study deals with preparation of FA aggregates. Artificial aggregates with FA (class C) and combination of fly ash and GGBFS were preparedTwo sorts of restoring techniques were embraced for aggregates. Restoring strategies incorporate water relieving and Chemical restoring (NaoH). The tests results the fly ash water cured and chemically cured aggregates were performed well, so these two types of aggregates were adopted for preparation of GPC mixes. The GGBFS replacement content in finalized as 30% from phase I results. The GPC mixes with 8 M, 10 M, 12 M NaoH Solution concentrations were cast using fly ash aggregates. Workability and strength test were done on the GPC samples. It was observed that GPC mix W6 attained a maximum compressive strength of 42.89 MPa among GPC specimens with water cured aggregates. It is observed that the specimens with chemically cured aggregates. It is observed that the GPC mix with chemical cured aggregate have better workability and bonding with the matrix
