INTRODUCTION:

Concrete, as a constructive material, has been used in construction industry for about two centuries.

The global production of ceramic tiles in the world is about 8500 million square meters, this amount is about 400 million square in Iran, which make Iran the fifth ceramic tile producer in the world.

Usually, The wastage related to tile, ceramic and sanitary waste are created in different forms some of which are produced in companies during and after production process due to errors in either construction, human activities ,and also inappropriate raw materials.

NEED OF STUDYPresently in ceramic industry the production

goes as waste, which is not undergoing the recycle process yet. It has been estimated that about 30% of the daily production in the ceramic industry goes as waste.

MATERIALS Used as a coarse aggregate, fine aggregate. The use of materials with pozzolan properties in cement

achieves: Economic Advantages: Reduced need for clinker production (lower energy

consumption). Environmental Advantages: Reduced CO2 emissions (Kyoto Protocol) Technical

Advantages: Long-term mechanical strength Stable resistance to expansion due to the presence of free lime,

sulphates and aggregate-alkali reactions. Durable resistance to the action of pure and acid water. Reduced hydration heat Impermeability, reducing porosity and increasing compactness.

PROCEDURE

The test specimens were cast in steel cubic moulds (150×150×150) and compacted on a vibrating table. After approximately 24 hours, the specimens were removed from the moulds. The concrete specimens were cured in lime-saturated water at 21ºC in cure tanks until the time of testing.

For each mix, cubic samples were tested to determine the compressive strengths at 7 and 28 days of curing. A 2000-kN capacity uniaxial compressive testing machine was used to compressive strength test.

The compressive strength, specific Wight and water absorption for each mixture was obtained from average of three cubic specimens.

Result In Ceramic WasteDifferent proportions of waste ceramic are use

as course aggregate in cement concrete to determine the compressive strength.

CONCLUSION Finally, the following results were obtained: 1. Using ceramic wastage in concrete

production causes no remarkable negative effect in the properties of concrete. The optimal case of using tile wastage as sand are amounts of 25 to 50 percent, besides, the best case of their use as coarse aggregate are as amounts of 10 to 20 percent. In these measures, not only an increase happens in compressive strength, but also a decrease in unit weight and lack of remarkable negative effect on water absorption is reported.

Continued………. 2. Using tile wastage in concrete leads to

removal of those materials from environment. Besides, decreasing the use of raw materials, using the wastage is considered positive economically.

3. Using tile wastage in concrete, with regard to reducing the costs and keeping the environment clean along with wastage management, and ameliorating the strength of structures, is an effective measure in sustainable development.
