Temperature Control in Bridge Tower Concrete Platform Construction and the Effect Analysis

混凝土凝固时发生水化反应释放热量,当混凝土结构尺寸超过一定限度时,混凝土内部热量不易及时散发,造成内外较大温度差,产生温度应力,导致混凝土开裂。文章以具体工程案例,通过温度分析,采取温度控制技术,有效地避免了混凝土裂缝出现,保证了工程质量。

Hydration reaction will release large amount of heat in concrete setting. When concrete structure is large to a certain extend, the heat generated inside cannot be easily distributed and temperature stress due to large temperature difference will lead to concrete cracking. Temperature analysis and temperature control introduced in the article can effectively avoid concrete cracking and guarantee the engineering quality.
