Various types of fibers like glass, steel, coconut fiber, sugarcane bagasse fiber, etc are used to increase the mechanical properties of the concrete. SCBF is the final residue of the sugar industries which is used in this study. The objective of the paper is to study the effect of SCBF in geopolymer concrete (GPC) and conventional concrete (CC) of equivalent grade of M40 when it is subjected to alternative drying and wetting. The specimens are treated with water by alternative wetting and drying process. This test consists of periodic cycles, each cycle consists of one wetting day and drying day. The specimens are tested for the compressive strengths after 7, 14 and 28 cycles. The compressive strength of the CCF and GPCF are higher than the CC and GPC respectively and the optimum compressive strengths are obtained at 0.5% of fiber dosage. The % loss of compressive strength and % loss of weights of CCF and GPCF are calculated and compared with the CC and GPC. From the results obtained, the strength loss and the weight loss in the CCF and GPCF are less when compared to the CC and GPC when treated in alternative wetting and drying process.

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.
