Durability of calcium-aluminate based binders for rapid repair applications
(2016-05)
Within the last few decades, the amount of vehicle miles traveled within the US has increased approximately 40% with the construction of new roads only increasing 4% during this same time period. This dramatic increase ...
Evaluation of concrete structures affected by alkali-silica reaction and delayed ettringite formation
(2012-08)
Alkali-silica reaction (ASR) and delayed ettringite formation (DEF) are expansive reactions that can lead to the premature deterioration of concrete structures. Both have been implicated in the deterioration of numerous ...
ASR expansion behavior in reinforced concrete : experimentation and numerical modeling for practical application
(2017-09-14)
Most practicing structural engineers are not well-equipped with the knowledge or tools necessary to adequately address the problem of alkali-silica reaction (ASR). While the mechanisms and consequences of ASR in plain, ...
Effects of alkali-silica reaction on the shear behavior of reinforced concrete beams without transverse reinforcement
(2016-08-10)
Alkali-silica reaction, or ASR, is a common deterioration mechanism that subjects concrete to internal expansive stresses. Previous research on the structural effects of ASR has shown that if a structure is effectively ...
Shear performance of ASR/DEF damaged prestressed concrete trapezoidal box bridge girders
(2010-08)
Concrete bridges in Texas have developed large cracks in bent caps and pretensioned trapezoidal bridge girders. The bridges show premature concrete deterioration due to alkali-silica reaction (ASR) and delayed ettringite ...
