Abstract |
In this paper, a comparative cold weather concrete member test was conducted with gang form and euro form, which are generally used as forms for construction in Korea. Three members were fabricated for the comparative test: the member with the general gang form and euro form, the member with the existing insulation gang form on the outside and the general form on the inside, and the member with the existing insulation gang form on the outside and the newly developed insulation euro form on the inside. In this test, ready-mixed concrete with a nominal strength of 24 MPa that met a certain standard was cast in the cold weather concrete condition at a temperature of 0℃ (5℃ ~?5℃), which is lower than the cold weather concrete management standard temperature in Korea 4℃ mean daily temperature. The standard water curing compressive strength, core compressive strength and temperature history were measured and comparatively examined for the general gang form-general euro form and insulation gang form-general euro form members that were cured at a certain inside temperature, and for the insulation gang form-insulation euro form member that was cured without additional temperature control. |
