摘要
混凝土电气加热蓄热升温、恒温、降温三个养护过程温度变化规律可用吴震东方程精确地描述 ,从而使混凝土在电极加热法有一套精确的热工计算公式。本文在文献〔5〕的基础上添补了电阻、电功率、计算公式一览表 ,对电极加热养护提出了设计与施工要求。
Law of variance in temperature can be accurately described by WU Zhendong equation in the three curing stage,rise in temperature, constant temperature and drop in temperature by electric thermal storage. Thus, there are a set of accurate calculation formulae of thermodynamics for heating curing of concrete with electrode in winter.Based on the document,the calculation formulae of resistance and electric power were subjoined ,and the requirements of design and construction for electrode-heating curing were put forward in this paper.
