The influence of the length of the construction period on the efficiency of a construction project is very important. In the process of construction and construction, affected by the natural climate, coupled with the progress of the construction of the project, sometimes it is inevitable to carry out winter construction, according to the winter of the construction project. The Construction Regulations (JGJ104-97) stipulates that when the outdoor daily average temperature is stable below 5 °C for 5 consecutive days, it will enter the winter construction. If the measures taken are improper, it will bring adverse effects to the construction project, and it is easy to give engineering. Quality causes hidden dangers or quality accidents, so building construction should be carried out at temperatures above 5 °C.
Because the strength increases mainly by hydration, when the water freezes, the hydration stops, and when the water freezes, the volume will expand, causing the concrete structure to loosely break. Therefore, when the average temperature in the day and night is below -5 °C Construction should be stopped. When the average temperature between day and night is between 5 ° C and -5 ° C, measures should be taken to protect it.
