C70高强高性能混凝土研究与应用

Research and application of C70 concrete with high intensity and high performance

随着建筑高度的不断增高,为了提高混凝土的耐久性,高强高性能混凝土应用在不断的增多。通过不同原材料的选择,应用矿粉和粉煤灰双掺技术,经过混凝土的性能测试,已确定C70混凝土的最佳配合比及工艺参数,通过三里屯SOHO项目的验证,证明是确实有效的方法,对高强高性能混凝土的研究与应用起到一定的借鉴作用。

With the height of building higher and higher,the longer endurance,better intensity and performance of concrete are required. Through selecting from different raw and processed materials,using double mix technology of fine powder and crushed coal dust,alter testing the performance of the concrete, the optimal formula and the technical parameters of C70 concrete are concluded.In the Sanlitun SOHO project, it is proved that the double mix technology is effective really, and it can be used as a reference for the high intensity and high performance concrete in the research and application field.
