Experimental Study on Ceramic Tiles Waste in Concrete Replacing of Coarse Aggregate

Concrete is a composite material composed of coarse aggregate bonded together with a fluid cement that hardens over time. Most concretes used are lime-based concretes such as Portland cement concrete or concretes made with other hydraulic cements, such as cement fondue. However, asphalt concrete, which is frequently used for road surfaces, is also a type of concrete, where the cement material is bitumen, and polymer concretes are sometimes used where the cementing material is a polIn construction industry the broken stones are highly used to produce concrete, it results to mining rock surfaces and hill zones to procuring coarse aggregate for the purpose of concreting the structures, to reduce the detoritation of nature. In this project we utlise ceramic waste to replace the aggregate in concrete. Clay minerals become highly reactive when they are heat incinerated at temperatures between 600-900°C and then ground to cement fineness. They are mainly formed by siliceous and aluminous compounds. The loss of water due to thermal treatments causes destruction of their crystalline structure, and they are converted into unstable amorphous state, If they are mixed with calcium hydroxide and water, they undergo pozzolanic reaction and form compounds with enhanced strength and durability. Therefore, they have a potential to be used in mortar and concrete. In this project, a wide range of parameters of concrete containing waste ceramics are used as replacing agent of coarse aggregate. Ceramic waste is one of the most active research areas that encompass a number of disciplines including civil engineering and construction materials. Ceramic waste powder is settled by sedimentation and then dumped away which results in environmental pollution, in addition to forming dust in summer and threatening both agriculture and public health. Therefore, utilization of the ceramic waste powder in various industrial sectors especially the construction, agriculture, glass and paper industries would help to protect the environment.
