Abstract

Concrete roof in In-Chon LNG tank #15~18 is a very important structure. Precise control of quality is needed. This roof has 0.6~1.5m thickness, 36.23m radius, and, 12.7m height. So in this structure thermal crack caused by hydration heat should be controled. In this project belite cement plus LSP concrete is used. As a result of ambient temperature rising test and thermal analysis using FEM, this belite cement plus LSP concrete is expected to control the thermal crack well.
