The Practical Application of High Strength Concrete to Major Structural Elements in consideration of Heat of Hydration

This paper presents the practical use of high strength concrete on 28-story Samsung Shin-dacbang Housing-Commercial Combined Building with 8-story basements located in Seoul. 700 Kg/$\textrm{cm}^2$ compressive Strength concrete was placed for basement core-walls and 500 kg/$\textrm{cm}^2$ concrete was used for structural frames up to 10th floor. The thermal sensors were installed prior to concrete casting into the core walls to measure the heat of hydration during hardening process. The correlation of core strength to the standard cylinder test strength was also discussed. The successful utilization of 500 and 700 kg/$\textrm{cm}^2$ concrete shows that the practical application of high strength concrete has a great potential to the high-rise R.C building construction.
