在寒冷地区通过掺加减水组分、早强组分、引气组分、防冻组分等复合外加剂使混凝土在受冻前达到抗冻临界强度,确保水泥混凝土在低温条件下强度继续增长并达到设计强度和耐久性要求,达到了延长施工时间、缩短施工周期的目的.
在寒冷地區通過摻加減水組分、早彊組分、引氣組分、防凍組分等複閤外加劑使混凝土在受凍前達到抗凍臨界彊度,確保水泥混凝土在低溫條件下彊度繼續增長併達到設計彊度和耐久性要求,達到瞭延長施工時間、縮短施工週期的目的.

It makes the concrete reach frost-resisting critical strength before freezing to add the composite admixture including water reducing components, early strength components, air-entraining agents and antifreeze components in the cold area, ensuring that the strength of concrete at low temperatures can continue to grow and reach the design value of strength and meet the requirement of durability, which can extend the construction time and shorten the construction period.
