ERMCO2015 Congress was held with great success, once more in İstanbul after twenty years. Participants from thirty countries on four continents made presentations on the latest trends in concrete production and the urgent needs in the field. We are proud to have hosted so many notable speakers from all over the world. Sixty one papers were submitted to the Congress, all of which were collected in a book as a future academic resource. We strongly believe that these organizations will lead the development and the innovation in the field of concrete. As Turkish Ready Mixed Concrete Association (TRMCA), we will always be part and pioneer of such organizations in the future.
