人工砂高性能混凝土配制技术研究

采用现代混凝土配合比设计理念,通过试验,研究了人工砂高性能混凝土配合比的设计原则。通过分析粉煤灰、石粉含量对人工砂高性能混凝土在工作性和力学性能上的影响,确定粉煤灰的最佳掺量和石粉含量的范围,结果表明人工砂完全可以替代天然砂配制高性能混凝土。

STUDY ON PRODUCTION TECHNOLOGY OF HIGH PERFORMANCE CONCRETE WITH ARTIFICIAL SAND

Using modern design concept of concrete mixture ratio,researches were made on the design principle of the mixture ratio of high performance concrete with artificial sand through tests.By analyzing the effects of the contents of flying ash and stone powder on the workability and mechanical properties of the high performance concrete with artificial sand,optimum contents of the ash and powder were determined.It shows that artificial sand can be completely used to produce high performance concrete in replacement of natural sand.
