Abstract


The aim of the present work was to utilize solid waste materials (organic and inorganic) in cementitious composites (CC) for the development of low-cost and energy efficient building materials. For this purpose, various organic (cotton, polyester, PET, carpet) and inorganic (glass and GBFS) wastes were incorporated in CC in different proportions and prepared CC tuff tiles using 1:6 w/w cement and sand, respectively. All the specimens were de-moulded after 24 h of their casting and were studied for curing period of 3, 7 and 28 days. After curing, the tuff tiles were tested for their bulk density, water absorption capacity and flexural strength using standard ASTM methods. The results showed that the incorporation of the selected wastes in the CC did not much affect their bulk density and water absorption capacity. However, these materials have changed the flexural strength of the resultant CC. Among the selected wastes, the inorganic wastes increased the higher flexural strength of CC as compare plain CC and CC incorporated with the organic wastes. The present work also provides a reliable step for the solid waste management and utilization and conversion of solid waste materials into useful commercial products.
