Ceramic dust is produced as waste from ceramic bricks, roof and floor tiles and stoneware waste industries. Concrete (M35) was made by replacing % (up to 30%) of cement (OPC 53) grade with ceramic dust (passing 75µm) shows good workability, compressive strength, split-tensile strength, flexural strength and elastic modulus. In this experimental investigation, concrete specimens were tested at different age for different mechanical properties. The results show that with water-cement ratio (0.46), core compressive strength increase by 3.9% to 5.6% by replacing 20% cement content with ceramic dust. It was observed that no significant change in flexural strength and split-tensile strength when compared to the conventional concrete.

The purpose of this paper is to evaluate the suitability of ceramic waste as a filler material in Semi-Dense Bituminous Concrete. A bituminous concrete mixes with ceramic dust and hydrated lime were prepared in different proportions (3% and 5%) as filler. The amount of optimum binder content was determined by Marshall Stability test for samples. The mechanical performance was determined for Marshall Stability, deformation behavior or flow, as well as for density and void characteristics base on prevailing Indian standards specifications. Results show that the stability values and other parameters of samples containing ceramic wastes are improved in comparison to conventional mineral filler. The benefits of using ceramic waste in bituminous concrete mixture as mineral filler (3-5%) are therefore recommended. The replacement of conventional filler like lime and other mineral in bituminous concrete by ceramic wastes will have major environmental benefits.
