Abstract :

In the present study, an investigation was conducted to evaluation of tile, brick, fire brick, plaster and concrete wastes derived from construction and demolition (C&D) wastes in Portland cement raw meal production as secondary raw material. Clinker test results showed that using of these wastes in cement was suitable. Then, cement production was performed with using 1, 2.1 and 3.9 wt. % mix C&D waste addition ratios in the cement factory. Desired phases like belite and alite, which are essential for the cement products, were observed at the micrographs. Also, obtained cement products supplied required and standard properties; however, strength and hydration heat values were lower. Finally, optimum C&D waste addition ratio was determined and results were found as practicable. It was shown that mix C&D waste materials can be utilized as secondary raw material in cement production.
