Utilization of Baby Diaper Waste and Corn Litter as Additives for Making Concrete Roof Tiles

Concrete tiles are an effective type of roofing, but they are relatively heavy, which affects the size of the lath, which needs to be larger and stronger, but this requires higher costs. On the other hand, the large amount of baby diaper waste and corn litter, which has not been widely utilized, encourages researchers to explore the use of baby diaper waste and corn litter as additives for environmentally friendly concrete roof tiles, which is expected to improve the quality of concrete roof tiles. The purpose of this study was to determine the physical, mechanical, and thermal properties of concrete roof tiles modified with baby diaper waste and corn litter. The research began with the preparation of baby diaper waste, corn litter preparation, and the production of test specimens, followed by a series of tests including density test, water absorption test, impermeability test, impact test, and thermal test. The results showed that the concrete tile test specimens of variation 1 had a density of 1.96g/cm 3 , water absorption of 12.6%, impermeability, impact strength of 3.81KJ/m 2 and flame value of 0mm/s. Variation 2 had a density of 1.27g/cm 3 , water absorption of 38.9%, water impermeability, impact strength of 2.34KJ/m 2 and flame spread of 0.166mm/s. Variation 3 has a density of 1.65g/cm 3 , water absorption of 14.9%, water impermeability, impact strength of 25.45KJ/m 2 and flash value of 0.053mm/s. Variation 4 has a density of 0.99g/cm 3 , an impermeability of 64%, a water impermeability, an impact strength of 1.91KJ/m 2 , and a flash value of 0.32mm/s. Variation 5 has a density of 1.31g/cm 3 , an impermeability of 31.8%, is waterproof, has an impact strength of 22.07KJ/m 2 and a flash value of 0mm/s. Finally, Variation 6 has a density of 1.25g/cm 3 , an impermeability of 32.3%, a water permeability, an impact strength of 9.55KJ/m 2 , and a flash value of 0mm/s.
