Abstract

The aim of this study is to investigate the effect of crushed ceramic waste as sand replacement in concrete design. In this experiment, the characteristic strength of the controlled sample is 25 MPA at 28 days. The percentages of crushed ceramic waste used to replace sand are 15, 30 and 45%. Previous studies by other researches [1, 2] had shown that, when used as partial replacement of coarse aggregate, the concrete produced has lower strength than the 100% natural coarse aggregate concrete (controlled sample). Other researcher[3] incorporate the crushed ceramic as partial sand replacement in mortar and the recorded result shows that the compressive strength and the resistance to abrasion increase as the content of crush ceramic increase up to 60% but the workability of concrete decrease with the increase content of crushed ceramic. This research is to study the effect of replacing partial content of sand with crushed ceramic to the compressive, flexural and split tensile strength of grade 25 concrete. Results show that the compressive strength (28 days) of crushed ceramic increase with the increase of crushed ceramic content. The increment is 8, 10 and 12% higher than the controlled sample for 15, 30 and 45% replacement and still maintained the slump within the limit (30 – 60 mm). The flexural and split tensile also exhibit increase in value with the increase of replacement content, which is 3, 5, 7% and 13, 20, 23% for the said test and content. Thus, it is suggested that crushed ceramic is used as partial replacement of sand, and not coarse aggregate, in application where the compressive, flexural and tensile strength could not be compromised for usage of grade 25 concrete with maximum content up to 45%..
