简化成熟度在粉煤灰混凝土同条件养护早期强度推定中的应用

Application of simplify-maturity theory in predicting early-age strength of fly ash concrete under the same curing condition

本文基于简化成熟度理论,试验研究了粉煤灰混凝土在模拟同条件养护下的早期相对强度发展情况,得出了其早期相对强度预测公式,并按照《混凝土结构工程施工质量验收规范》(GB50204-2002)的相关要求,对该类混凝土等效养护龄期及同条件养护至600℃.d时的相对强度进行了具体分析。

Based on the simplify-maturity theory,this paper investigated the early-age strength of fly ash concrete under the same curing condition imitated to the structure.The early-age relative strength-simplify maturity equation was concluded from this research and the relative strength when simplified maturity reached 600d was discussed.We also analyzed effective curing age conformed to the new version of GB50204-2002.
