补偿收缩新材料在首都新机场墙体结构中的应用

Research of the long-term mechanical properties of polyvinyl alcohol fiber concrete

介绍了一种可以同时补偿混凝土干燥收缩与温度收缩的新型膨胀材料,具有膨胀效率高、降低水化热温升等特点,在首都新机场航站楼地下室的大平面墙体结构中的应用取得了不错的效果,再次印证了吴中伟院士关于'干缩与冷缩联合补偿'的理论。

It introduces a new type of expansive material which can simultaneously compensate the drying shrinkage and temperature contraction of concrete.It has the characteristics of high expansion efficiency and low temperature rise of hydration heat.Application in the large-scale wall structure in the basement of the new airport terminal building has achieved good results,once again confirmed Academician Wu Zhongwei on'shrinkage and action compensation'theory.
