Ceramic Waste Powder as a Partial Substitute of Fly Ash for Geopolymer Concrete Cured at Ambient Temperature

The growth of the construction industry has expanded demand for ceramic building products such as tiles, which constitute essential materials. Nonetheless, a huge quantity waste powder is produced during polishing tiles. disposal key environmental concern that needs to be properly addressed. purpose this research evaluate potential recycling geopolymer binder. main objective consists exploring impacts two types (vitrified tiles and wall tiles) on partial substitution fly ash in concrete. For this, concrete was prepared under ambient conditions without oven curing. Slump, compressive strength, split tensile modulus elasticity tests were performed measure workability mechanical properties Its durability evaluated through water absorption sorptivity tests. microstructural behavior investigated using scanning electron microscopy X-ray diffraction measurements. investigation revealed 15% replacement by wall-tile gave similar 3% increase 7% improvement elasticity. Partial with vitrified reduced improved microstructure findings can used replace 10–15% M35 grade structural concrete, cured conditions. Doi: 10.28991/CEJ-2022-08-07-05 Full Text: PDF
