摘要

•Cold joint can form for placement intervals less than initial setting time.•Concrete becomes unworkable when the penetration resistance is more than 0.5 N/mm2.•The re-vibration limit appears between 0.4 and 0.6 N/mm2 penetration resistance.•Cold joint forming resistance is independent from the ambient temperature.
