摘　　要：根据崇启大桥实际环境要求进行混凝土配合比设计并展开力学性能研究,试验结果表明,F40组混凝土各龄期强度均高于F60,F30S30,F40S20,混凝土粉煤灰最佳掺量为30%～40%,磨细矿渣的掺入提高了混凝土抗折性能。According to the factual environmental requirements of Chongqi Bridge, the paper undertakes the mix proportion design of the concrete and carries out the research on the dynamic performance, and proves by the experimental results that all the age strengths of F40 group concrete are higher than the ones of F60, F30S30 and F40S20, and the optimal mixing amount of concrete fly ash is between 30% to 40%, and the mix- ture with the ground slag can improve the anti-fold capacity of the concrete.
