Factors affecting concrete durability are various and complex. And the number of parameters that characterize the status of durability is large. It's not easy to eliminate error from numerous data and find out the internal law among them. However, it's convenient for one database management system to manage and dispose of data so as to evaluate and forecast concrete durability. This paper briefly discusses the virtues of the object-oriented programming-VB6.0 for database and factors resulting in damage of concrete durability, introduces carefully the structure and function of DurDBMS. At the end of the paper, an instance is set up to transact carbonate and the result reveals that the error of prediction meets with request of experiment, quantitative analysis accords with that of qualitative.
