粉煤灰对高性能混凝土工作性的影响研究

Research on fly ash affected to workability of high performance concrete

研究了粉煤灰掺量对混凝土工作性的影响,研究结果表明,在40%掺量范围内,随着粉煤灰掺量的增加混凝土的流动性增大,掺入粉煤灰能明显改善混凝土坍落度的经时损失。还分析了粉煤灰对混凝土工作性的影响机理。

The paper researched the workability of the concrete influenced by the fly ash quantity mixed.The research results showed that within the 40% quantity of the fly ash mixed,as the fly ash mixed increased,the fluidity of the concrete will be increased and the fly-ash mixed can obviously improve the slump timing loss of the concrete.The paper analyzed the influence mechanism of the fly ash to the workability of the concrete.
