[Purposes] To study the compressive performance of silane-containing emulsion marine engineering concrete bridge piers (referred to as EMC-PIER). [Methods] Ten EMC-PIER specimens were fabricated in batches with varying silane emulsion content, length-to-diameter ratio, and eccentricity as parameters. They were subjected to eccentric compression tests to analyze their failure modes. Additionally, the calculation accuracy of the eccentric compression ultimate bearing capacity of EMC-PIER was compa
