Assessment of Fly Ash and Polypropylene Fibre on Environmentally Sustainable Precast CC Paver Blocks

The paver blocks are produced from zero slump plain concrete is a small element used for outdoor applications and flexible road surfaces. Depending upon the traffic intensity these are fabricated with various thicknesses, dimensions and shapes to meet the requirement of various applications. Within this research grade, M30 paver blocks with OPC replaced with 30% fly ash and a 60 mm and 80 mm thickness and the inclusion of PPF at 0.0–0.5% with increments of 0.1% by weight of binder (cement) have been produced to test the suitability of Indian road surfaces for various purposes. The blocks underwent strength and durability testing at ages 7 and 28 days. For strength compressive strength and flexural strength tests of the material's characteristics were performed; both are crucial for uses on road surface. The results of compressive strength and flexural strength show that substituting it for Ordinary Portland Cement is practical with Thirty percent fly ash & add 0.3% PPF while making paver blocks. At 28 days, all grades of paver blocks have reached the desired compressive and flexural strengths. Present study is important for paver block manufacturers as it meets the objectives such as mix design, strength and durability requirements for Indian roads associated with the utilization of waste material fly ash. Also, the study will help the nation's economy at a 20% level in future, along with virgin materials’ sustainability.
