Mechanical Properties Of Polypropylene Fiber Based Geopolymer Concrete

Abstract The second most consumed product in the world is Cement, which is main reason for the carbon dioxide emission. Geo polymer concrete (GPC) is becoming a special type of eco-friendlier concrete &alternative to Ordinary Portland Cement (OPC). This project deals with the effect of class F fly-ash & ground granulated blast furnace slag (GGBS) on the mechanical properties of Geo Polymer Concrete (GPC) by volumetric fractions of 0%, 0.1%, 0.2% & 0.3% of POLYPROPYLENE Fiber (PPF). The effects of inclusion of POLYPROPYLENE fiber on compressive strength, flexural strength & Split tensile strength of hardened Geo polymer concrete are being studied. Fly ash to GGBS ratio was fixed to 50:50 with 100% replacement of OPC by fly ash and GGBS. Alkaline liquid consists of sodium hydroxide (NaOH) and sodium silicate (Na2SiO3) solutions. Additional super plasticizer is being used for high workability. POLYPROPYLENE fibers were added to the mix with the lengths of 6mm POLYPROPYLENE fibers is mixed in volume of concrete. The mix design which has been used is M30 grade of concrete. Main purpose of this project is to bring out the advantageous results of Geo polymer concrete comparing with fiber-based Geo polymer concrete.
