Casting and curing of concrete at elevated temperature would decrease its compressive strength.
拌和及养护的温度高,混凝土抗压强度低。
However, the hydration degree of binder, as well as the adiabatic temperature rise for high strength concrete, will be obviously decreased due to the increase of initial casting temperature.
但却会明显降低高强度等级混凝土所用胶凝材料的水化程度,使其绝热温升值下降。
This paper states the viewpoint that the exceeding long temperature crack and settlement crack in concrete structure can be solved by later casting zone.
混凝土结构中经常遇到超长的问题,本文就混凝土结构超长的温度缝和沉降缝是否均可设后浇带解决的问题,阐述了自己的观点。
