研讨了负温高强泵送混凝土配合比的设计计算步骤，并给出了Ｃ５０～Ｃ６０级负温高强泵送混凝土配合比计算实例。可供施工单位进行冬期施工计算配合比时参考。
The design and calculation steps of the mixing ratio of negative temperature high-strength pumping concrete were studied, and the calculation example of the mixing ratio of C50-C60 negative temperature high-strength pumping concrete was given. It can be used as reference for the construction unit to calculate the mix ratio for winter construction.
