ABSTRACT: This study proposes a rational CRCP construction system using prefabricated steel mesh panels and high early-strength concrete. The greatest concern in CRCP is the possibility of excessive cracking, which can cause steel corrosion. The yielding of steel bars may occur during excessive cracking owing to the volume change of the concrete at an early age. The constructability and cracking properties of the CRCP should be examined in advance. In this study, a field test of CRCP (110 m long × 11.5 m wide) was conducted to examine the constructability and observe concrete cracking. This paper presents CRCP construction using prefabricated steel mesh panels and high-early strength concrete and reports concrete cracking and steel strain observed from field tests.
