A certain project is located in the severe cold zone of northwest China.
Due to the special nature of the project, tight schedule, and heavy workload, it needs to be constructed all year round, and a large amount of concrete pouring operations need to be carried out normally in winter.
Currently, research on concrete construction in cold regions both domestically and internationally is mostly focused on raw materials, mix proportions, and insulation, temperature measurement, and curing, with relatively little research on other aspects of the entire construction process.
However, this project has strict requirements for the performance of concrete, and the raw materials and mix proportions cannot be changed arbitrarily.
It also needs to have frost resistance and durability.
Conventional winter construction measures are difficult to meet the needs, so special research is needed.
