AN ASSESSMENT OF THE PROPERTIES OF CONCRETE MADE WITH CERAMIC WASTE AS AGGREGATE

Building Technology Project Topics And Materials

ABSTRACT

 
The quantity of ceramic waste tile in Nigeria has been on the increase without consideration for potential reused or recycling. This increases the risk to public health due to the scarcity of land area. The growing problem can be solved if new disposal option other than landfill can be found. Continuous dependence on conventional materials for concrete is also leading to scarcity of its materials resulting to increase in construction cost. This research was carried out to establish the suitability of ceramic waste tile as aggregate for concrete production. Ceramic waste tile originate from broken, scrap and leftover tiles. The replacement proportion was 100% for both fine and coarse natural aggregates. A total number of 100 cubes were cast using nominal mix ratio of 1:2:4 with water cement ratio of 0.55 and tested for compressive and split tensile strength at 7, 14, 28 and 56 days. Abrasion resistance and water absorption tests were carried out at 28 days of curing age. The results showed that at 28 days the compressive strength was 22.27N/mm2 and 19.46N/mm2, and split  tensile strength of 2.94N/mm2 and 1.94N/mm2 for ceramic waste tile concrete and that of conventional concrete. This research concludes that the ceramic waste tile concrete has a higher strength and durability than conventional concrete and also recommends that the ceramic waste tile can be used as an alternative construction material for fine and coarse aggregate
