摘要：
An experimental investigation was carried out to study the influence of constituent materials on concrete durability. Three groups of concrete specimens with silica fume/fly ash were cast and tested. In this study, compressive strength test, water absorption test, rapid chloride penetration test（RCPT）, chloride ion diffusion test and gas permeability test were performed. Various test results were compared. It shows that the water/binder ratio is still a key factor to influence the durability of concrete. The application of pozzolanic materials can reduce the permeability and improve the mechanical properties of concrete, and silica fume is more beneficial than fly ash. Besides, the cement content and aggregate size are also significant factors affecting concrete durability.
