摘要:Different fibers like steel, glass, basalt, coconut, sugarcane fibers are used to improve the tensile strength in the concrete. The sugarcane bagasse fiber (SCBF) is utilized in this paper work. This SCBF is the final extract of the sugar industries which contains the large fibers. The main objective of this paper is to study the effect of SCBF on the permeation properties of the geopolymer concrete (GPC) of G40 and compared to its equivalent M40 grade. The specimens of conventional concrete (CC) and conventional concrete with SBF (CCF) are casted and cured in the curing tanks for a period of 28 day, and the GPC and GPCF specimens are casted and oven cured at a temperature of 60OC for a time period of 24 hours and the test are performed after 28 days of ambient curing of the specimens. The permeation test like (Water absorption test, Sorptivity and Water Permeability test) are carried in the paper. Based on the results it is observed that the permeation properties of CCF and GPCF are more resistant when compared to the CC and GPC respectively.
