Mechanical and Durability Study of Steel Fiber-Reinforced Geopolymer Concrete
The global use of concrete is second only to water. As the demand for concrete as a construction material increases, so also the demand for Portland cement. It is estimated that the production of cement has increased from about from 1.5 billion tons in 1995 to 2.2 billion tons in 2010. So it is inevitable to find an alternative material to the Portland cement whose manufacturing process is most resource consuming. The utilization of supplementary cementing materials such as fly ash, silica fume, granulated blast furnace slag, rice-husk ash has encouraged the researchers to develop alternative binder paste to completely replace cement paste. Geo polymer concrete is an innovative construction material which shall be produced by chemical action of these inorganic amorphous binders. In this we make use of supplementary cementitious materials which react with alkaline activators to form Al-O-Si-O gel which has similar bonding strength as C-S-H gel. Geopolymer concrete itself is very brittle so to increase its flexural and tensile strength Fibers have been incorporated. In this work durability study was performed on the geopolymer concrete with steel Fibers by curing them in harsh chemical environment, it was observed that there was slight reduction in density and compressive strength of GPC exposed to the chemical solutions like HCl and H2SO4 than concrete in ambient condition, which was only about 1.4% and 0.76% respectively. These results indicate that the geo polymer concrete has shown better performance under harsh environment when compared to normal concrete.
