Investigation on the Appropriateness of Ceramic Waste Materials at Hawassa Ceramics Factory as Partial Replacement of Conventional Aggregate in Concrete Making

Abstract

Conservation of natural assets and environment is the core of any development. Nowadays, the waste material disposal is the major problem for the development of any technology and industry. As a researcher found that the constructive waste materials are appropriate for the production of concrete, this brings down the cost of concrete and protected disposal of waste materials can be easily achieved. In ceramic industry factories around 30% to 50% of production goes as waste material, which is not recycled. So in this research paper, a laboratory investigation has been conducted to evaluate the suitability of ceramic waste material at Hawassa Ceramics Factory at Hawassa as the major partial replacement of conventional aggregates in concrete making. In the laboratory, both fine and course aggregates are partially replaced by the ceramic scrap. In the case of fine aggregate substitution, 50% of the fine aggregate was replaced, and in the case of coarse aggregate substitution, 33.3% of the course aggregate was replaced. Totally, there were 6 concrete cubes samples casted for both type of aggregate and laboratory test for compressive strength conducted after a curing period of 3 and 7 days. The effectiveness of the partial replacement of both fine and course aggregates of ceramic waste by 50% and 30% discussed in the research study.
