摘要
研究了粉煤灰掺量对C50高性能混凝土HPC工作性、抗压强度以及干缩的影响。试验结果表明：粉煤灰掺量在10％～20％范围内，提高了混凝土的工作性能、后期抗压强度，降低了混凝土的干缩值。
This paper studied the impact of fly ash on the workability, compressive strength and dry shrinkage of C50 high-performance concrete. The results showed that the performance of the concrete and its late compressive strength were improved, the drying shrinkage value reduced when fly ash was mixed with 10%-20%.
