ABSTRACT:
Aggregates and Cement, which are the most important constituents used in concrete production, are the most essential materials needed for the construction industry. This certainly led to a continuous and increasing demand of natural materials used for their production. A large quantity waste is produced annually in the world especially in the construction industry. Because, construction and demolition waste contribute the highest percentage of construction waste. Furthermore, ceramic materials contributes the highest percentage of waste within the construction industry and demolition waste of about 54%. In order to be environmentally friendly post-use, it was considered desirable to use this large amount of waste enumerating from construction industry as a useful raw material to replace coarse aggregate, while mixing the concrete, we used a m ix ratio of 1:2:4, and a water-cement ratio of 0.55 due to the compressive strength of the concrete. We replaced the coarse aggregate with ceramic tiles in three batches plus one batch of the concrete while served as control mix, so as to compare their properties with the aid of some tests. The replacement was in 10%, 15% and 25%. The concrete molds were cast and tested for compressive strength and split tensile strength after a curing period of 7, 14, 28 days. The result shows that increasing maximum compressive and split tensile strength are achieved as replacement percentage increased at 5% interval, the 25% replacement was the maximum in the study.
