在广州合银广场工程中 ,通过施工模拟试验及工程应用实践制定了钢管柱Ｃ80高性能混凝土施工工法 ,实践证明是可行的。1 特点(1 )通过掺入高效减水剂、细磨矿渣、Ⅰ级粉煤灰配制Ｃ80高性能混凝土。(2 )制定了完善的施工工艺及质量控制措施 ,混凝土质量稳定 ,2ｈ坍落度损失控制?
In the project of A & P Plaza in Guangzhou, the C80 high performance concrete construction method for steel pipe column has been established through construction simulation test and engineering application practice. Practice has proved that it is feasible. 1 Features (1) C80 high-performance concrete is prepared by mixing superplasticizer, finely ground slag and Grade I fly ash. (2) Has developed a perfect construction technology and quality control measures, the quality of concrete stability, 2h slump loss control?
