摘　　要：为探讨青藏高原严酷环境下粉煤灰掺量对混凝土强度的影响,在室内模拟青藏高原干冷、干热的环境条件,对C60混凝土的配制与施工中粉煤灰掺量对混凝土强度的影响进行了试验。通过干冷养护、干热养护与标准养护环境的对比试验表明,粉煤灰掺量在25%时为宜,同时在施工时应做好混凝土的养护工作,以确保混凝土的强度。The asperity condition of Qinghai - Tibet Plateall is simulated by indoor test and the formulation of C60 high perfonnance concrete and the influence of flyash mixed on concrete strength are also tested. The results of standard curing enviroment experiment and dry- cold, dry- hot curing enviroment experiment show that the suitable quantity of flyash mixed is 25 % and the curing work must be done to enhance the concrete strength in construction stage.
