Abstract:

The chemical constituents in the cement and aggregates play a key role in the durability of concrete structures. High alkali contents in cement, especially Type III cement, when used with reactive siliceous aggregates (which are prominent in Texas) in the presence of moisture can result in alkali-silica reaction (ASR). ASR can lead to the formation of expansive by-products, which in turn can lead to cracking of the concrete. Concrete cracking from ASR can lead to other deterioration processes, such as delayed ettringite formation (DEF) and corrosion, which can further reduce the capacity of the structure. Most cases of premature concrete deterioration within the Texas Department of Transportation (TxDOT) bridge inventory have been identified or at least suspected to be primarily from ASR. An area of concern for TxDOT is the structural performance of column splice regions with varying levels of premature concrete deterioration due to ASR and DEF.
