利用深圳当地材料进行了一系列C80高性能混凝土的室内试验 ,并成功地在高层建筑中进行了中试应用 .研究结果表明 ,采用常规原材料和普通生产工艺 ,可成功地制备出 2 8d抗压强度 90～ 1 0 0MPa、坍落度达 2 5cm且 2h无坍落度损失的C80高性能混凝土
A series of C80 high-performance concrete in-house tests were carried out using local materials in Shenzhen and successfully pilot-operated in high-rise buildings.The results show that using conventional raw materials and ordinary production processes, C80 high performance concrete with strength of 90 ~ 100MPa, slump of 25cm and no slump loss for 2h
