Abstract
In this research, a fuzzy system has been presented to predict the behavior of self-consolidated concrete (SCC) under tidal conditions in Sea of Oman. As the coastal concrete structures are subjected to chloride attack, it is highly essential to consider their compressive strength. For this purpose, in order to define the fuzzy membership functions, a number of SCC specimens of different w/c ratios, different percentages of micro-sio2 and nano-sio2 were made and placed on the coast of the Sea of Oman at different ages. These concrete specimens were covered with nets and subjected to sea tidal condition. After that, a fuzzy system was defined which includes four input functions: w/c ratio, age, amount of micro-sio2 and nano-sio2. The output function was the compressive strength of the concrete. In this fuzzy system, Mamdani inference engine was used. Ultimately, this system was able to predict the compressive strength of self-compacting concrete under tidal condition with high accuracy and with only an 3% difference.
