Superior activity is an important property of self leveling mortar, contented superior activity ability enough leveling buildings of mixed condensate disk, remove traditional air unyielding and shortcomings, then stop laying wooden floors, carpets, tiles and other practices air decoration materials. Follow the foreign dry mixed mortar skills in China continuously carry out and use, the superior performance of cement based airborne gravity anomaly data gradually gained the recognition at home and abroad of relevant enterprise. But although the cement-based self leveling mortar has a lot of advantage, but in order to achieve superior task performance and stability of the average initial hardening function needs the skill performance of the mortar, the formula composition and other aspects into the deeper research. In the future, there are high cost in the application and construction of the world. Is the important topic in gravity high Shan Ping data of raw materials from the hands, proceed with the mortar's cost problems, on the one hand application of slag powder added into the self leveling mortar as a filler, and replaced it with a department of cementitious mat on the other hand applied directly through the screening of the blast furnace slag as self leveling mortar aggregate, research the floor mortar to bring the influence of, through the process of all kinds of additives adjust, open up a suitable to industrial production and cost of self leveling air products. Through the process of industrial waste residue in Wuhan iron and Steel Group to reach the double benefit of the economy and the situation. Through the process of research notes of slag powder and sand mixing can obtain superior performance of air self leveling mortar. The contents and results of the experimental study include: 1. The domestic SM series water reducing agent has excellent performance ratio, and can achieve better performance and mechanical performance. Also in assessing bone incorporation will quantitative coarse sand can not only modified mortar and mortar can increase mechanics performance. II slag powder than the eve of the area in the 350m2/kg can display superior activity. At the same time, all replaced Shuangfei powder as filler can obtain better mechanical performance. 3 of the mortar strength along with the dosage of cement growth continuously growth, the selection to the ordinary portland cement and sulphoaluminate cement amount to 18% and 12% can be achieved superior price. Acquisition of slag sand as aggregate strength is higher than the traditional quartz sand and slag sand and quartz sand joint application than Lingding application a aggregate high strength. Fifthly, through different corrosion agent influence of self leveling mortar strength that, DB g retarder in not only has good activity and may greatly improve the mortar mechanical function, when the incorporation of 0. 3%, the compressive strength of 28d can reach 38. 8MPa.目录:摘要4-5Abstract5-61 绪论10-26&&&&1.1 自流平材料的分类与市场现状10-14&&&&&&&&1.1.1 水泥基自流平材料10-11&&&&&&&&1.1.2 石膏基自流平材料11-12&&&&&&&&1.1.3 环氧树脂地坪涂料12-13&&&&&&&&1.1.4 聚氨酯地坪涂料13-14&&&&1.2 国内外水泥基自流平材料的发展现状14-15&&&&1.3 国内外水泥基自流平材料研究现状15-19&&&&1.4 地面用水泥基自流平砂浆性能19-23&&&&&&&&1.4.1 地面自流平砂浆的组成19-21&&&&&&&&1.4.2 自流平砂浆满足的技术规范21-23&&&&1.5 地面自流平砂浆研究的意义23-24&&&&1.6 课题研究的内容和采取的技术路线24-26&&&&&&&&1.6.1 研究内容24-25&&&&&&&&1.6.2 拟采取的研究方法、技术路线25-262 实验材料和实验方法26-29&&&&2.1 实验材料26-28&&&&&&&&2.1.1 水泥26&&&&&&&&2.1.2 石膏26&&&&&&&&2.1.3 砂26&&&&&&&&2.1.4 双飞粉和矿渣微粉26-27&&&&&&&&2.1.5 外加剂27-28&&&&2.2 试验方法28-29&&&&&&&&2.2.1 标准试验条件28&&&&&&&&2.2.2 流动度试验28&&&&&&&&2.2.3 保水性实验28&&&&&&&&2.2.4 机械性能实验28&&&&&&&&2.2.5 尺寸变化率28&&&&&&&&2.2.6 拉伸粘结强度28&&&&&&&&2.2.7 耐磨性28-293 水泥基自流平砂浆外加剂的适应性29-37&&&&3.1 减水剂对砂浆的适应性研究29-34&&&&&&&&3.1.1 Flo对砂浆流变性能的影响29-30&&&&&&&&3.1.2 进口聚羧酸系列减水剂对砂浆流变性能的影响30-32&&&&&&&&3.1.3 国产聚羧酸减水剂对砂浆流变性能的影响32-34&&&&3.2 正交试验34-36&&&&&&&&3.2.1 正交因素水平34&&&&&&&&3.2.2 正交试验结果34-36&&&&3.3 结论36-374 矿渣微粉对砂浆性能的影响37-46&&&&4.1 矿渣微粉作为填料取代双飞粉37&&&&4.2 矿渣微粉比表面积对砂浆性能的影响37-39&&&&4.3 碱性激发剂对砂浆性能的影响39&&&&4.4 石膏种类对自流平砂浆的影响39-40&&&&4.5 矿渣微粉和水泥比例调节对自流平砂浆性能的影响40-45&&&&&&&&4.5.1 水泥量调整对砂浆性能的影响40-42&&&&&&&&4.5.2 矿渣微粉取代普通硅酸盐水泥对砂浆性能的影响42-43&&&&&&&&4.5.3 水泥中普通硅酸盐水泥和铝酸盐水泥比例的调整43-45&&&&4.6 结论45-465 矿渣砂对砂浆性能的影响46-57&&&&5.1 不同骨料对自流平砂浆的影响46-51&&&&&&&&5.1.1 各种砂对砂浆性能影响46-49&&&&&&&&5.1.2 矿渣砂和石英砂配合使用49-51&&&&5.2 外加剂对矿渣砂自流平砂浆的影响51-56&&&&&&&&5.2.1 不同聚羧酸减水剂对矿渣砂自流平砂浆的影响51-52&&&&&&&&5.2.2 缓凝剂对矿渣砂砂浆的影响52-54&&&&&&&&5.2.3 高掺量矿渣体系自流平砂浆性能的优化54-56&&&&5.3 总结56-576 结论和展望57-59&&&&6.1 结论57-58&&&&6.2 展望58-59致谢59-60参考文献60-63附录63原价:¥20.00元折价:¥5.00元分享到:相关文献|自流平_列表网问答
