摘要
大体积混凝土由于温度差而产生温度应力并导致温度裂缝开展,温度裂缝将影响结构的防水性和耐久性,严重时还将影响结构的承载能力,因此在大体积混凝土施工中合理控制混凝土温度裂缝将是提高混凝土浇筑质量的关键因素。
Because of the temperature difference, the mass concretes may produce the temperature strain and result in the temperature cracks, the temperature cracks could affect the architecture's waterproofing and durability function, what is more, it could affect the architecture's load support capability. So controlling the concrete temperature cracks rationally is the key factor to improve the irrigating quality of the concrete in the mass concrete construction.
