摘要
为了解高强度混凝土水化热温度的特点 ,从而为今后同类材料结构的温度控制打下基础 ,本文采用实测数据研究与理论分析相结合的方法 ,比较了高强度混凝土与普通混凝土在绝热温升和实测温度值方面的区别 ,论述了水化热温升对高强度混凝土强度发展的不利影响和对高强度混凝土冬季施工的有利影响 ,并讨论提出了高强度混凝土的温度控制标准 .文章认为 ,对厚度超过 1m的高强混凝土构件 ,应当采取相应的温度控制措施 ,控制构件的最高温度不超过 70℃ ,构件内外最大温差不超过 30℃ .
In order to know the characteristic of heat of hydration on high strength concrete and to prepare for temperature control on structures with the same material, this paper combines field measurement method with theoretical analysis method, contrasts high strength concrete with common concrete on adiabatic temperature rise and on field measurement temperature, elucidates the disadvantage of temperature rise on strength development of high strength concrete and the advantage of temperature rise on winter construction of high strength concrete, discusses the temperature control criterion of high strength concrete. At last, the paper points out that for high strength concrete components more than 1 meter wide, it is needed to control the maximum temperature below 70?℃ and the maximum thermal differential below 30?℃.
