Basic applicability of an insulated gang form for concrete building construction in cold weather

In cold weather, construction sites typically find it difficult to achieve quality results when preparing concrete structures. In such construction projects, improper selection of the formwork for concrete placement can delay the project schedule and result inconsiderable expense. In this study, rigid urethane board was bonded to the exterior surface of a conventional gang form to ensure sufficient compressive strength of the concrete structures in cold weather. To verify the applicability of the insulated gang form, the temperature history, maturity, and characteristics of strength development of the concrete were examined and compared with the conventional type after the concrete had been placed.
