Strength properties of ceramic waste concrete

Today significant research study is ongoing into the use of waste materials like, fly ash, GGBS, waste glass powder etc. as Portland cement replacements. A ceramic waste powder is used as a binder with partial replacement of cement which takes some part of reaction at the time of hydration, and also it acts as a filler material. This study is focused on the waste ceramic powder used as a replacement to the concrete ingredient i.e. cement and the strength properties like compressive, split tensile and flexural strengths were measured and the size effect of ceramic waste powder on strength of concrete. To check the strength effect of replacement of cement by ceramic waste powder, the cement ingredient in concrete is replaced at 10%, 20%, 30%, 40% and 50%. This paper focuses on the size effect of ceramic waste powder, having a size less than 90 micron and another size ranges from 90 microns to 150 microns. For this study, concrete mixtures were prepared, for low-grade M20 and medium grade M40. Strength studies like compressive, split tensile and flexural strengths were conducted and comparisons have to be made with the conventional concrete.
