摘　　要：利用青藏高原环境模拟试验室,通过干热养护与标准养护对比试验,对青藏高原干热条件下粉煤灰掺量对混凝土强度的影响进行了试验研究。实验结果表明:C60混凝土粉煤灰掺量以25%为宜,C30混凝土粉煤灰掺量为33%为宜;并提出了相关建议。The influence of the adding quantity of coal ash to the concrete strength under the hot and dry condition in Qinghai-Tibet plateau was studied in the Qinghai-Tibet plateau environment laboratory through a comparing experiment between hot and dry curing and standard curing. The result shows that the adding quantity of C60 concrete coal ash should be 25 % and 33 % for C30 concrete coal ash and related opinion was put forward too.
