粉煤灰对深井煤矿巷道隔热材料性能的影响

THE EFFECT OF FLY ASH ON THE HEAT PROFF MATERIAL USED IN THE DEEP MINE LANEWAY

通过粉煤灰对隔热材料流动性、力学性能、热性能及耐久性的研究 ,指出低活性粉煤灰降低了隔热材料的流动性、强度及耐久性 ,却提高了材料的隔热性能 .对材料强度的测试结果表明 。

Reseach on the effect of fly ash on the fluidity,mechanicas performance,thermal performance and ageing resistance of the heat proof material,the author point that low activated fly ash decreased the fluidity,strength and ageing resistance of the heat proof material,but increased its heat prof performance.The testing results of material strength indicated that the low activated fly ash would not decrease the long term strength of heat proof material.
