摘要
运用成熟度理论,对施工同条件养护下的掺粉煤灰的混凝土试件进行了试验。对比分析了粉煤灰对混凝土成熟度与相对强度关系的影响。并按照《凝土结构施工质量验收规范》(CB50204-2002)中关于同条件养护的相关规定,对成熟度为600℃.d时的相对强度f做了具体的分析。
The fly ash concrete specimens are tested with the same curing condition as construction by using maturity degree theory in the paper.The influence of fly ash on relationship between concrete maturity degree and relative strength is compared and analyzed.The relative strength at 600℃·d maturity degree is analyzed concretely according to related regulations of the same curing condition according to GB50204-2002.
