拆模的试块如果3天能达到强度,压出来的试块数值有效吗? - 工程施工 - 项目管理 - 氿上知道

满意答案
2、拆模试块的作用是了解砼结构的强度是否达到规定允许拆模的强度。(GB50204规定:跨度大于8m的梁,应达设计强度的100%、小于等于8m的梁,
应达设计强度的75%以上、悬臂构件应达100%时,方可拆模。
3、砼结构强度的评定,以标养试块和同条件试块的数据为准。因此,拆模试块的数据是判断是否可以拆模的参考,不能作为评定依据。
4、你说三天即达到设计强度,一般情况下是不可能的,除非特殊砼。
5、标养试块是经28天标准养护后试压,同条件试块是在与现场构件
相同养护条件下,达到400度*天时试压。
