  • Study on time intervals for placing on consolidated fresh concrete of bridge slabs

抄録

<p>During placing of concrete, it is necessary to pay attention to the time interval of placing concrete to prevent cold joints from occurring. For this reason, the STANDARD SPECIFICATIONS FOR CONCRETE STRUCTURES-2017 [Materials & Construction] defines 2.5 hours as the standard allowable placing on consolidated time interval when the outside temperature is below 25℃. In this case, concrete is placed in separate top and bottom sections. Bridge has thin deck slab and the connection is at an angle. We report on the investigation regarding the time interval of fresh concrete for bridge deck slab.</p>
