In this experimental investigationcompressive strength and water absorption of paver block were evaluated by replacing portion of cement with the GGBS (Ground Granulated Blast Furnace Slag). Polyester Triangular fibers were also incorporated along with the GGBS to further enhance the mechanical properties. Different proportions of Polyester Triangular fiber starting from 0.4% and 0.5% by weight of materials. 20% to 35% by weight of cement was replaced with the GGBS. By test testing the specimen optimum fibre and GGBS content find out.
