水化热 [化学] heat of hydration
hydration heat
- 大体积混凝土在桥梁施工过程中,由于水泥水化热容易引起表面裂缝。
During the mass concrete construction in bridge structure, the cement hydration heat is easy to cause surface cracking. - 混凝土的早期收缩包括:塑性阶段的收缩和硬化初期的水化热冷缩与干燥收缩两部分。
Concrete shrinkage include: the early stage of plastic shrinkage and hardening of the early hydration heat and cold and dry shrinkage two parts. - 控制拱坝的裂缝是拱坝设计中必须认真解决的问题,而消除施工期水化热温升的不利影响,是碾压混凝土高拱坝设计中的关键。
To remove the unfavorable impact caused by the temperature rise of hydration heat during the construction period is key to the design of high RCC arch dam.
