天津高银117大厦超高泵送混凝土的研制及工程应用

Development and Engineering Application of Ultra-high Pumping Concrete of Tianjin Gaoyin 117 Building

以中国结构第一高楼天津高银117大厦为载体，调整细骨料比例及用量、粉煤灰水泥用量、浆体量及外加剂组分配制超高泵送C60混凝土。通过扩展度、倒锥时间及压力泌水率参数评定混凝土的泵送性能，效果优异。

Taking the China＇ s tallest building structure Tianjin Gaoyin 117 Building as the carrier, the ratio and the amount of fine aggregate, the amount of fly ash and cement, the amount of slurry and additives are formulated to prepare ultra-pumping concrete C60. The slump flow, inverted cone time and the rate of pressure bleeding are used to evaluate concrete pumping performance, and the result is excellent.
