In Sweden, castings occur all year round, similar to all other countries in the world.However, since Sweden have fairly low temperatures in most months of the year, winter casting becomes a hot topic to talk about. Winter casting is largely followed by many measures to prevent early freezing in mature concrete. A critical success factor during the construction phase is to take off the formwork at the adequate strength and at the right time. The concrete must reach adequate strength without additives otherwise the formwork is left standing longer than required, which has a major impact on the schedule and budget. Therefore, companies and contractors strive to complete this task in an orderly manner to minimize construction time and design costs. The study’s great emphasis is to scrutinize and compare the forecasted simulations byprogram PPB against measured values of temperature development and strength growth that was measured in the concrete from the casting time up to a few days later. The comparison will test how effective PPB is to forecast the heat evolution in concrete after casting, especially during the winter.The methods used to achieve the result are:A temperature register from the thermocouples that measures the heat evolution in concrete.Forecasting of construction elements that have the same properties and conditions as in reality.Literature studies that describe the methodology for this necessity. Results of the work indicate promising success for the program after multipleconformities between measurement values and simulations. Additionalrecommendations and documentations were provided for better results.
