Abstract
Abstract:
The Self-Compacting Geo Polymer Hybrid Fiber Reinforced Concrete (SCGPHFC) is widely
developing concrete in the construction industry which is eco-friendly and sustainable concrete. In this
concrete, the materials involved are Fly ash (FA), Ground Granulated Blast Furnace Slag (GGBS) and
Metakaolin (MK) which acts as a building material. These materials act as binders and reduce the
emission of CO2 from the construction industry. Fly Ash is a by-product obtained from thermal power
plant which has more alumina-silicate content, where fly ash is completely replaced by cement which
is alternative binder to the concrete. The fly ash is replaced by 10% with GGBS and Metakaolin which
enhances the pozzolanic reaction and form geo-polymerization. The addition of SCGPC with the hybrid
fiber i.e., combination of two fibers, the total amount of fibers is 1.5% of the powder content which
represents the Self-Compacting Geo Polymer Hybrid Fiber Reinforced Concrete (SCGPHFC). A slump
cone, L-Box test and V-Funnel test are conducted to evaluate the fresh properties of the concrete.
Compressive Strength, Split Tensile Strength and Flexural Strength are conducted to evaluate the
hardened properties of the concrete. For the durability properties acid attack, rapid chloride ion
permeability test (RCPT) and Resistance to Concrete. The mix SCGPHFC5 i.e., 0.75% of steel & PVA
fiber showed the greatest improvement in all the tests conducted among all the mixes. As the dosage of
fiber is constant the chloride ion penetration was reduced. The results for the concrete mix SCGPHFC
5 shows have attained high strength values compared to the other mixes of SCGPHFC.
