Modeling of Bond Stress–Slip Relationships of a Strand in Concrete during Steam Curing

Songhee Lee Jeongha Oh The restrained thermal expansion of a pretensioned strand causes thermal prestress loss during steam curing until sufficient bond strength develops. The amount of thermal prestress

Modeling of Compressive Strength Development of High-Early-Strength-Concrete at Different Curing Temperatures

Songhee Lee Ngocchien Nguyen High-early-strength-concrete (HESC) made of Type III cement reaches approximately 50-70 % of its design compressive strength in a day in ambient conditions. Experimental

Optimization of Curing Regimes for Precast Prestressed Members with Early-Strength Concrete

Early-strength-concrete (ESC) made of Type I cement with a high Blaine value of 500 m2/kg reaches approximately 60 % of its compressive strength in 1 day at ambient temperature. Based on the 210 compressive test results, a generalized rate-constant material model was presented to predict the development of compressive strengths of ESC at different equivalent ages (9, 12, 18, 24, ...
