EXPERIMENTAL STUDY ON STRENGTH ASPECTS OF GEOPOLYMER CONCRETE WITH FORTA FERRO FIBERS

Geopolymer1 concrete (GPC) is a green concrete of sodium hydroxide2 , sodium silicate, fly ash and ground granulated blast furnace slag (GGBS) 4 . The use of GPC reduces CO2 in the atmosphere which leads to the reduction of green gases globally. In the past most of the research work has been done on the usage of GPC with different molarities such as 6 M, 8M, 10M, 12M, 14M, etc. From research findings done in the past, a molarity3 of 12 has been considered in the current investigation. In the proposed GPC mix the fly ash has been replaced by GGBS in various proportions in order to get the optimum dosage of GGBS in fly ash. To overcome the deficiencies in concrete, in the present study Forta Ferro Fibers (FFF) 5 have been incorporated in various percentages to achieve the optimum dosage. In the present study M40 grade concrete is considered to study the strength aspects of GPC with FFF such as compressive strength, cylindrical split tensile strength and flexural strength. Experimental results shown that the strength GPC with FFF was significantly higher than that of conventional concrete.
