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.

Introduction The Indian ceramics industry, which is comprised of wall and floor tiles, sanitary ware, bricks and roof tiles, refractory materials and ceramic materials for domestic and others use is producing approximately 15 to 30 MT per annum waste. Out of total waste, 30% goes as waste in India and dumped the powder in open space. Ceramic waste is of generally two types, waste earthenware and also cracked during the manufacturing process. Ceramic waste is considered as non-hazardous solid waste and possess pozzolanic properties. Therefore, after recycling can be reuse in different building construction application [1,2,3,4,5]. Industrial wastes coarser than cement particles generally use as fine and coarse aggregate in concrete mix up to 35% tile waste [6,7]. The use of waste as an alternative to aggregate in highway construction would produce two major benefits; firstly, the natural aggregate quarry life can be extended. Secondly, the consumption of industrial space or productive land for dumping such waste may be reduced. The Indian concrete pavement are essentially jointed plain cement concrete with dowel bar of mild steel. The pavement quality concrete (PQC) for road slab (thickness varies from 290 to 350 mm) is mainly M40 and M35. Dowel bars are provided across transverse joints for load transfer and longitudinal joints are to connects adjoining lanes to relieve warping stresses. The PQC slab is generally placed over a layer of low grade dry lean concrete (DLC) of 150 mm thickness. A 125 mm thick antifriction polythene layer is used in between PQC and DLC [8,9]. Researchers used ceramic waste to make green concrete by using minimum 20% replacement natural aggregate. It was found that ceramic waste based concrete shows good workability and achieve characteristics strength. The permeation characteristics of green concrete is also reported as similar to the conventional concrete durability [10,11,12,13]. Use of non-hazardous industrial waste is also gaining popularity in India to use in building construction work for developing building material components. The waste was used in cement concrete up to 20% of conventional coarse aggregate is due to high absorption coefficient (0.5%) and achieved compressive strength approximately 50Mpa with and without super plasticizers additives [14,15,16]. Ceramic waste as a replacement of natural aggregate in concrete slab shows good abrasion resistance and tensile strength with confirmation of relevant standard. Ceramic waste used in road sub-base layer as filler and in PQC reached strength 40-50 Mpa. Even ceramic waste was also used to replace fine aggregate and found good compressive strength and abrasion resistance, together with less penetration by chlorides which could provide greater protection for the reinforcement used in reinforced concrete. Researches suggested that more than 20% replacement of natural coarse and fine aggregate with ceramic waste will decrease the compressive strength of the concrete. The reuse of ceramic waste in concrete road is viable and economical option to achieve target strength M35 after 28 days curing. Apart from replacing natural aggregate in concrete, ceramic waste also used in replacing cement percentage in concrete as additive, in the light of pozzolanic properties. Result shows that concrete used ceramic powder, possesses satisfactory mechanical and durability [17,18].
