Maintenance for Repaired RC Column Exposed to Chloride Attack Based on Probability Distribution of Service Life

Sang-Hwa Jung Hyun-Min Yang Keun-Hyeok Yang Seung-Jun Kwon Chloride attack is one of the most critical deterioration due to rapid corrosion initiation and propagation which can cause structural safety

Shear Stress-Relative Slip Relationship at Concrete Interfaces

Flexural Behavior of Post-tensioned Lightweight Concrete Continuous One-Way Slabs

In this experimental study, six post-tensioned light weight concrete (LWC) continuous one-way slabs were tested in the following manner: the flexural behaviors of the members were compared with the calculations from the existing standards. The test also examined the effect of prestressing in tendons and proper prestress conditions to reduce the deflection and crack width, and to...

Comparison of Strength–Maturity Models Accounting for Hydration Heat in Massive Walls

The objective of this study was to evaluate the capability of different strength–maturity models to account for the effect of the hydration heat on the in-place strength development of high-strength concrete specifically developed for nuclear facility structures under various ambient curing temperatures. To simulate the primary containment-vessel of a nuclear reactor, three 1200...

Carbonation Characteristics of Alkali-Activated Blast-Furnace Slag Mortar

Alkali-activated ground granulated blast-slag (AAS) is the most obvious alternative material for ordinary Portland cement (OPC). However, to use it as a structural material requires the assessment and verification of its durability. The most important factor for a durability evaluation is the degree of carbonation resistance, and AAS is known to show lower performance than OPC. A...
