The effect of glass fiber on fresh properties of industrial based geopolymer concrete

This research study is primarily focused on evaluating the fresh properties of industrial-based 3D printable geopolymer concrete by adding glass wool strings and fibers activated sodium silicate solution with a molar ratio 2.4-2.6 (31 % SiO 2 13 Na O). The strings, recycled fiber are added to at dosage 1 5 volume concrete. such as open time, setting time shape stability (GPC) were compared those GPC without fibers. results show that addition increases mix room temperature. deformation specimens temperature decreased 39 %. in geopolymers also stiffness 74 fiber.
