一、混凝土试件的代表性是有条件的混凝土质量通常依靠试件强度评定,再配合以外观检查。以标准养护试件的强度值代表混凝土的固有的或潜在的强度特性,并做为工程验收依据;认为在正常施工之下,实际工程结构中的混凝土是可以表现出这个固有的强度特性的。其随同工程结构一起养护的试件,则根据需要用来 First, the representation of concrete specimens is conditional. The quality of concrete is usually assessed by the strength of the test specimens, and in conjunction with the visual inspection. The strength values ​​of the standard curing specimens represent the inherent or potential strength characteristics of the concrete and serve as a basis for engineering acceptance; it is believed that under normal construction, the concrete in the actual engineering structure can exhibit this inherent strength property. The specimens that are maintained along with the engineering structure are used as required
