Individuals from the group of inorganic polymers are known as geopolymers. The geopolymer material's compound organisation is similar to that of typical zeolitic materials, however the microstructure is undefined rather than translucent. The polymerisation interaction includes a considerably quick substance response under antacid condition on Si-Al minerals and that meets the basic properties of concrete as well as falls under classification of manageability. Utilization of various fibres like steel, glass, sugarcane bagasse etc, significantly influences fresh and hardened properties of concrete. Sugarcane bagasse fibre is a by-product from sugar industries and can be used as a fibre in concrete. The target of this paper is to study an effect of sugarcane bagasse fibre on mechanical properties such as compressive, tensile and flexural sgength and also the workability of low calcium fly ash (Class-F) and slag based geopolymer concrete of G40 grade which is équivalent to M40.. Sugarcane baggase ash fibre has been used for both the concencrte G40 and M40 as 0.5%,1%,1.5%,2%. All the samples were casted and oven cured at 60o for 24 hours after one day rest period and remaining days cured in an ambient temperature, then tested on 3rd, 7th and 28th day to assess the mechanical properties, such as Compressive, Tensile, and Flexure strength. The results were compared among controlled concrete (CC), controlled concrete with sugarcane bagasse fibre (CCF), geopolymer concrete (GPC) and geopolymer concrete with sugarcane bagasse fibre (GPCF). The results revealed that with addition of SCBF, the mechanical properties have been enhanced significantly.
