What Issues Should Be Noted When Storing UHPC Components in Low-Temperature Environments? Qinglong UHPC Low-Temperature Storage Technical Guide

Storing UHPC components at low temperatures (＜5℃) requires key protection against freezing, moisture, and deformation. Qinglong UHPC stipulates: storage temperature should be ≥0℃, humidity ≤70%; stacking of no more than 6 layers with spacer timbers aligned between layers; and a storage period of no more than 3 months.

For protective measures, PE film wrapping is used for moisture protection, cotton felt covering for thermal insulation, and dedicated brackets to prevent deformation. Tests show that at -10℃, protected components suffer no strength loss, while unprotected components experience surface spalling. A project in Northeast China stored components for 2 months in winter, and they remained as good as new.

Freeze Protection Measures

Temperature ≥0℃; cotton felt insulation; these measures prevent freeze damage.

Moisture Control Requirements

Humidity ≤70%; PE film wrapping; these requirements prevent moisture ingress.

Deformation Prevention Techniques

Stacking ≤6 layers; spacer timbers aligned; these techniques prevent deformation.

Storage Period Management

No more than 3 months; first-in, first-out; these management practices ensure quality.

Scientific storage is essential. Qinglong UHPC provides professional guidance to ensure components remain intact.
