摘要
通过对国内外实际工程中已经应用的高性能混凝土配合比进行分析和归纳,提出了高性能混凝土配合比胶浆体积固定在340~360L左右为最优的观点。并依此原理设计出大流动粉煤灰泵送混凝土配合比设计方法,通过数十个工程实践验证了这一方法的优越性。
The match ratios of high performance concrete in domestic and international the engineering application are analyzed and concluded.The optimal match ratio of high performance concrete is put forward with fixed grout volume at about 340～360 liter.According to this principle,the match ratio of ash concrete used pumping with high flowing is designed.The design method is verified through the several engineering project applications.
