This article uses indoor experiments to study the influence of the heating power of the electric heating wire outside the prestressed pipeline on the temperature of the cement slurry inside the pipeline under different environmental temperature conditions. The impact mechanism of the heating power on the peak hydration temperature and peak temperature time of the cement slurry inside the pipeline is analyzed. The relevant research results can provide data support for the grouting construction of prestressed concrete pipelines.

This article uses indoor experiments to study the influence of the heating power of the electric heating wire outside the prestressed pipeline on the temperature of the cement slurry inside the pipeline under different environmental temperature conditions. The impact mechanism of the heating power on the peak hydration temperature and peak temperature time of the cement slurry inside the pipeline is analyzed. The relevant research results can provide data support for the grouting construction of prestressed concrete pipelines.
