畢業(yè)論文/論文格式 動植物檢疫畢業(yè)論文參考文獻(xiàn)內(nèi)容 【論文內(nèi)容】 在朱曉敏研究基礎(chǔ)上,*以礦渣為礦物摻合料,用正交試驗(yàn)方法探討礦渣摻量以及堿量對合成粉煤灰地聚合物材料強(qiáng)度的影響。以礦渣或沸石為礦物摻合料,在常溫下合成粉煤灰地聚合物材料,用快速法研究該合成材料的堿集料反應(yīng)性能,正交法分析其脆性,測長法討論其體積穩(wěn)定性,以及參照國外mcc-1方法研究該材料的吸附重金屬能力,并用電子探針分析手段分析該吸附體的微觀結(jié)構(gòu)和組成,以此為該材料的實(shí)際應(yīng)用奠定基礎(chǔ)。 正交試驗(yàn)強(qiáng)度結(jié)果表明在常溫下合成的材料具有較高強(qiáng)度,其28d抗折強(qiáng)度為7.18mpa,抗壓強(qiáng)度達(dá)到27.72mpa,堿量是影響粉煤灰地聚合物材料強(qiáng)度的主要因素,其次是礦渣,且礦渣的摻入可以促進(jìn)粉煤灰地聚合物材料的合成,提高合成材料的早期強(qiáng)度。 脆性分析表明堿量對摻礦渣材料脆性的影響占主要地位,但礦渣對材料脆性,有一定的影響,且礦渣摻量增大,材料脆性增大;沸石摻量對摻沸石材料脆性的影響占主要地位,沸石的摻入會增大材料脆性,但堿的影響也不可忽視。 堿集料反應(yīng)結(jié)果表明該材料具有優(yōu)良的抗堿集料反應(yīng)能力,對堿集料反應(yīng)具有很好的抑制效果;收縮試驗(yàn)結(jié)果表明該材料的收縮比硅酸鹽水泥稍大。 固化重金屬離子試驗(yàn)表明材料具有吸附并固化溶液中重金屬離子的能力,且不同配比地聚合物材料的吸附能力不同,材料可以考慮作為廢水處理材料。電子探針分析結(jié)果表明吸附能力不同的粉煤灰地聚合物材料中產(chǎn)物的結(jié)構(gòu)形態(tài)不同。 【英文摘要】 based on the studies of fly ash geopolymer materials by zhu xiaomin, the effects ofblast furnace slag used as mineral supplementary, calcium oxide and sodiumhydroxide as alkali activators on the strength of geopolymers are studied byorthogonal test in the paper. the fly ash geopolymer materials are synthesized usingslag or zeolite as mineral supplementary under normal temperature of which the alkaliaggregate reaction (aar) is studied by accelerated method and the brittleness isanalyzed by orthogonal test, while the volume stability is investigated by determiningthe length of the samples in different curing time. and also the immobilization ofheavy metal in the material is discussed in the paper. the electron probemicroanalyzer is used to analyze the microstructure and the compositions of thesorption body. these results will be beneficial to the application of the fly ashgeopolymer materials.the strength results of orthogonal test show that the synthesized material is of relatively high strength (the compressive strength is 27.72mpa and flexural strength is 7.18mpa on the 28th day), which is influenced mainly by the dosage of cao and the concentration of naoh solution and slightly by the dosage of slag. but the slag can accelerate the synthesis and improve the early strength of the material. the brittleness analysis results reveals that the amount of the alkalis is the main factor influencing the brittleness of the synthesized material with slag but the slag will increase the brittleness of the material when the dosage increases, while the dosage of zeolite is the main factor and the alkalis is the secondary factor in the material with zeolite and the zeolite will increase the brittleness of the material when the dosage increases, but the effect of the alkalis cannot be ignored.the results of aar test indicate that the resistance of the material to aar is excellent and the material can restrain expansion of aar when used in corrosive environment. the research on the volume stability reveals that the shrinkage of the material is slight higher than portland cement.- 1.請仔細(xì)閱讀文檔,確保文檔完整性,對于不預(yù)覽、不比對內(nèi)容而直接下載帶來的問題本站不予受理。
