Presentation Title Quantifying Material, Environmental, and System Variables Influencing the Structural Performance of Reinforced Concrete Structures Affected by Alkali Silica Reactions

On-Site Speaker (Planned) David Trejo
Abstract Scope Contractors use high cement contents in concrete to accelerate the strength gain and reduce project construction time. Higher cement contents result in higher early strengths (HES). HES can result in earlier form removal, economic benefits to the contractor, and reduced project duration. Although the short-term benefits can be positive, longer-term challenges have arisen when high cements contents have been used. On a recent project owners recognized longitudinal cracking in columns. Investigations indicated that columns were exhibiting alkali silica reactions (ASR), likely a result of higher cement contents. Limited information is available on predicting performance and service life of structures exhibiting ASR. Therefore, this research investigated the structural performance of large-scale columns subjected to different levels of ASR. The researchers also assessed the performance of smaller-scale laboratory specimens. This paper reports on the influence of material characteristics, exposure conditions, and design parameters on the system performance and models are developed.
