问我们单位是一个小型建筑施工单位,没有试验室。在没有标准养护试块的情况下,可以用自然养护试块的抗压强度值对照规范相应图表来推算28天的强度值,作为检查评定构件混凝土强度的依据吗?
Asked us that the unit is a small construction unit and there is no laboratory. In the absence of standard maintenance test blocks, can use the compressive strength values of the natural curing test blocks against the corresponding charts of the specifications to calculate the 28-day strength values, as a basis for checking the strength of the assessed component concrete?
