This document discusses using ceramic waste as an aggregate in concrete. It presents the results of an experiment replacing regular aggregate with 10-40% ceramic waste aggregate. The highest compressive strengths were achieved with 10-30% replacement. Replacing over 30% resulted in lower strengths. The conclusion is that ceramic waste can be effectively used in concrete as both sand and coarse aggregate up to certain percentages without negatively impacting strength properties. This reduces waste in the ceramic industry and costs for raw materials in concrete production.

3. 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.

4. NEED OF STUDY
Presently 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.

5. 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.

6. 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.

10. 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.

11. 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.
