Alkali-silica reaction (ASR) and delayed ettringite formation (DEF) are two causes of concrete deterioration through concrete expansion and cracking. This paper describes the method used to approximate the damage caused by ASR/DEF by mechanically cra

Emulsifiable oils are often used in posttensioned construction to reduce friction losses and provide temporary corrosion protection for tendons prior to grouting. This paper addresses the effects of two emulsifiable oils and three duct types on bond

Corrosion protection for bonded, internal, posttensioning tendons (PTTs) can be effective. Within structural elements, PTTs can be well protected by a multilayer system that includes sound design of surface treatments; high-quality concrete; corrosio

A series of fresh property tests and accelerated corrosion tests were used to develop grouts that combine favorable grouting properties with good corrosion protection. The grouts were then pumped into a clear duct with multiple drapes to observe thei
