摘要(Abstract)：
在试验的基础上 ,研究了粉煤灰代替部分砂和水泥应用于井下巷道锚喷支护混凝土配料的可行性 ,讨论了粉煤灰混凝土抗压强度的主要影响因素及变化规律。结合井下初步应用性检验 ,确定了粉煤灰作为喷射混凝土掺合料的最佳掺量和配合比。
Feasibility of fly ash substituted for sand and cement in shortcreting is studied based on a lot of laboratory tests,as well as the main influence factors and rules of compressive strength of fly ash concrete are also discussed.Finally,the optimal recipes of fly ash applied to shortcreting concrete are decided by practice tests.
