摘要: |
A durability design method that has been used to quantify the requirements for reinforced concrete is described. It specifies the data required and decisions that need to be taken to achieve the specified performance. Codes and standards currently used for design are insufficient to ensure the long-term durability of structures in aggressive environments. Specific environmental data are a prerequisite for the modeling processes used to predict the performance of different mix designs. Selecting suitable materials is vital to ensure that performance is achieved and may necessitate that the concrete producer adopt more stringent performance requirements than those demanded by the specification. Mix design trials must consider the performance aspects of the specification and particular site characteristics. In extremely severe environments, concrete alone may not be sufficient to ensure durability performance, and additional protective measures may be necessary. |
