1、动植物检疫毕业论文参考文献内容 【论文内容】 在朱晓敏研究基础上，本文以矿渣为矿物掺合料，用正交试验方法探讨矿渣掺量以及碱量对合成粉煤灰地聚合物材料强度的影响。以矿渣或沸石为矿物掺合料，在常温下合成粉煤灰地聚合物材料，用快速法研究该合成材料的碱集料反应性能，正交法分析其脆性，测长法讨论其体积稳定性，以及参照国外mcc-1方法研究该材料的吸附重金属能力，并用电子探针分析手段分析该吸附体的微观结构和组成，以此为该材料的实际应用奠定基础。 正交试验强度结果表明在常温下合成的材料具有较高强度，其28d抗折强度为，抗压强度达到，碱量是影响粉煤灰地聚合物材料强度的主要因素，其次是矿渣，且矿渣的掺入可以促进
2、粉煤灰地聚合物材料的合成，提高合成材料的早期强度。 脆性分析表明碱量对掺矿渣材料脆性的影响占主要地位，但矿渣对材料脆性，有一定的影响，且矿渣掺量增大，材料脆性增大;沸石掺量对掺沸石材料脆性的影响占主要地位，沸石的掺入会增大材料脆性，但碱的影响也不可忽视。 碱集料反应结果表明该材料具有优良的抗碱集料反应能力，对碱集料反应具有很好的抑制效果;收缩试验结果表明该材料的收缩比硅酸盐水泥稍大。 固化重金属离子试验表明材料具有吸附并固化溶液中重金属离子的能力，且不同配比地聚合物材料的吸附能力不同，材料可以考虑作为废水处理材料。电子探针分析结果表明吸附能力不同的粉煤灰地聚合物材料中产物的结构形态不同。 【英
3、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
4、 are synthesized usingslag or zeolite as mineral supplementary under normal temperature of which the alkaliaggregate reaction 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 diff
5、erent 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 strengt
6、h results of orthogonal test show that the synthesized material is of relatively high strength , 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
7、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
8、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 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.
