| Abstract: | The effect of air-entering agent, expanding agent and water-reducing agent on the durability of concrete is studied with an engineering example. The results of the three agent admixtures show that they have excellent resistance to freezing, thawing cycling, permeability and cracking. The need of the durability of concrete buildings is satisfied. A new way for the study of admixture proportions and the durability of concrete used in ocean engineering is provided based on experience. |
