Abstract:
Two kinds of system have been considered in
this study. 100% replacement of cement by flyash and
100% replacement of river sand by manufactured sand. The
workability of Self Compacting Geo polymer Concrete
(SCGC) for various molarities and hardened properties of
SCGC were investigated in this paper. The work focused
on the concrete mixes with a fixed water-to-geopolymer
solid (W/Gs) ratio of 0.33 by mass and a constant total
binder content of 450 kg/m3. The workability related
fresh properties for molarity of 8M, 10M, 12M, and 14M
of SCGC were assessed through slump flow,T50cm Slump
flow, V-funnel, L-box and U-Box test methods. According
to EFNARC (European Federation of National Associations
Representing for Concrete) guidelines the mix
proportions are arrived. Based on the results taken from
workability tests the optimized molarity is chosen for
SCGC. The hardened properties of concrete are conducted
by replacing flyash with silica fume and GGBFS.
