全国冬季施工网编制的混凝土防冻剂质量管理中规定要求防冻剂产品应均匀、稳定,质量应满足“掺防冻剂混凝土的质量标准”,其中有:掺防冻剂混凝土在规定负温下养护28天后转标养28天,混凝土的抗压强度应大于或等于基准混凝土标养28天的强度。这对施工单位要尽快获得混凝土的实际 The regulations for the quality management of concrete antifreeze prepared by the National Winter Construction Network require that antifreeze products should be uniform and stable, and the quality should meet the “quality standard for concrete mixed with antifreeze agents”. Among them: the antifreeze mixed concrete is cured at the specified negative temperature for 28 days. After raising the standard for 28 days, the compressive strength of the concrete should be greater than or equal to that of the standard concrete for 28 days. This is the actual situation for the construction unit to obtain the concrete as soon as possible
