为了研究粉煤灰、矿粉对嵌缝胶泥性能的影响,对粉煤灰、矿粉不同龄期不同掺量的嵌缝胶泥进行抗折、抗压强度试验。并使用SEM、压汞仪分析其微观机理。试验表明:粉煤灰、矿粉在等量取代嵌缝胶泥中的水泥之后,其抗折抗压强度随掺合料掺量的增加呈现下降趋势。双掺粉煤灰矿粉组的微观测试结果显示其最可几孔径小于单掺粉煤灰矿粉组,且双掺组后期的水化产物丰富,有利于后期强度的增长。
為瞭研究粉煤灰、礦粉對嵌縫膠泥性能的影響,對粉煤灰、礦粉不同齡期不同摻量的嵌縫膠泥進行抗摺、抗壓彊度試驗。併使用SEM、壓汞儀分析其微觀機理。試驗錶明:粉煤灰、礦粉在等量取代嵌縫膠泥中的水泥之後,其抗摺抗壓彊度隨摻閤料摻量的增加呈現下降趨勢。雙摻粉煤灰礦粉組的微觀測試結果顯示其最可幾孔徑小于單摻粉煤灰礦粉組,且雙摻組後期的水化產物豐富,有利于後期彊度的增長。

In order to study the fly ash and mineral powder on the properties of cement sealing,Experimental research on different age, different content of fly ash and mineral powder to cement caulking compressive strength.And use the SEM ,mercury injection apparatus to analyze its microcosmic mechanism.Experiment shows that the fly ash and mineral powder after sealing isometric substitute cement in the cement caulking, the flexural compressive strength with the increase of the dosage of admixture showed a trend of decline.Double mixing fly ash mineral powder group of microscopic test results show that the most probable aperture smaller than single mixing fly ash mineral group,and double mixing group later hydration products is rich,is conducive to the growth of the late strength.
