Analysis of Hydration Heat Characteristics in Fiber-Reinforced Cement Concrete Bridge Deck Pavement Construction
摘要
Abstract
To analyze the hydration heat behavior and conduct finite element numerical simulations of fiber-reinforced cement concrete(FRCC)bridge deck pavement construction,a comparative study is performed on the hydration heat characteristics of conventional C50 concrete pavement during similar construction processes.The results indicate that central measurement points more accurately reflect the overall tempera-ture distribution.FRCC exhibits prolongs hydration heat release and superior thermal insulation under low-temperature conditions,attributes to its distinct mix design and cementitious system compared to C50 con-crete.C50 concrete requires stringent measures to prevent environmental temperature differential-induced cracks.Both materials reach peak temperatures 12～15 hours post-pouring.However,C50 concrete simula-tions exhibits greater temperature differentials compared to field measurements,likely due to low-tempera-ture construction and curing constraints.These findings provide actionable references for on-site construc-tion protocols and thermal crack prevention in practical engineering applications.关键词
