Alkali-silica reaction in concrete containing recycled concrete aggregates

Creator:

Adams, Matthew P.

Abstract:

Using recycled concrete aggregate (RCA) as a replacement for natural aggregate in new concrete is a promising way to increase the overall sustainability of new concrete. This has been hindered, however, by a general perception that RCA is a sub-standard material due to the lack of technical guidance, specifically related...

The role of alumina in the mitigation of alkali-silica reaction

Creator:

Warner, Skyler J.

Abstract:

The use of fly ash as a supplementary cementitious material (SCM) has increased in the last century due to its various environmental benefits as a recycled product. Within the last 60 years, it has been found that it can be used to effectively control damage induced by Alkali-Silica Reaction. However,...

Synergistic Effects of Alkali Silica Reaction (ASR) and Fly Ash on the Corrosion Characteristics of Reinforced Concrete Systems

Creator:

Mazarei, Vandad

Abstract:

Alkali silica reaction (ASR) and corrosion of reinforcement are two deterioration mechanisms in reinforced concrete (RC) structures. These deterioration mechanisms can significantly damage a RC structure and reduce its service life. Supplementary cementitious materials (SCMs) are commonly used to improve the durability of RC systems containing reactive aggregate that are...
