大专建筑毕业论文 屯化沥青防水涂料及混合料在水工中应用的试验毕业论文 【论文内容】 根据沥青混凝土在水利工程中的应用前景以及阳离子乳化沥青在公 路上广泛应用, 本文提出了以乳化沥青为基料的水工防渗材料的研究， 因为用乳化沥青施工具有重要的意义 : (一) 节约能源。使用乳化沥青 施工比用热沥青施工节省了大量的能量。(二) 节省资源。阳离子沥青 乳液与酸性和碱性骨料都有好的粘附效果, 从而扩大了人骨料的来源， 可就地取材, 减少材料费用。{三) 延长施工季节。在阴雨或者低温季 节, 乳化沥青也能施工, 从而延长施工时间, 缩短工期。(四) 改善了施 工条件, 减少环境污染。乳化沥青防渗材料是指用乳化沥青与矿料拌 和而成的材料。 乳化沥青失入矿物胶体乳化剂并与无机物填料拌和成 的材料就称为乳化沥青防水涂料;乳化沥青与骨料和矿粉拌和而成的 材料就称为乳化沥青混合料。本文对乳化沥青防渗材料的配方、拌和 成型以及性能进行了研究, 具体试验研究如下 : (1) 沥青的乳化乳化 沥青的质量对乳化沥青防渗材料的性能影响较大。因此, 本文采用试 验室沥青乳化方法, 选择复合乳化剂摸索出乳化条件, 并在此条件下 乳化出不同浓度的乳化沥青, 同时检验乳化沥青的基本性能, 确保乳 液的性能合格。(2)乳化沥青防水涂料本涂料选用乳化沥青、丙乳、  水泥作为原材料, 按照先加乳化沥青, 再加丙乳, 最后加水泥的投料顺 序拌和成涂料。并采用不同配方的乳化沥青防水涂料进行各项性能试 验测试其结果, 尤其是测试涂料的粘接强度、剪切强度以及渗透系数。 (3)乳化沥青混合料首先按公路工程的乳化沥青混合料试验方法选出 矿料的级配及配方、乳液用量、拌和用水量, 然后按顺序拌和成混合 料并成型, 最后在养护条件下养护, 测其室阶率。 检测结果不满足水工 防渗的技术要求, 因此确定公路上所用的矿料级配及配方不能直接用 于水利工程。本文用与热沥青混凝土类比的方法选定矿料的级配、源 青用量以及水泥用量(根据需要), 并拌和成乳化沥青混合料, 成型马 鞭尔试件和条形试件, 测其变形性能以及渗透性能。通过对本课题的 研究得出:乳化沥青防水涂料可以作为水工防渗材料;而普通乳化沥 青混凝土不能作为防渗层材料, 水泥乳化沥青混凝土需要进一步研究 确定其能否作为水工防滩层材料。 【英文摘要〗 According to application prospect of bituminous concrete in hydro-project and wide application of positive emulsified asphalt in highway engineering，studies that emulsified asphalt is used as fundamental material of water proof material for hydrostructure are brought up in this article，because it is important sense of using emulsified asphalt construction。 First，practise sources of energy: using emulsified asphalt construction saves plenty of sources of energy by comparison of using hot bituminous concrete  construction。Secondly，practise resources: positive emulsified asphalt has good effect of adherence with acidic aggregate and basic aggregate，and to expand Tesources of aggregate，use indigenous raw materials，cut down expense of material. Thirdly，delaying construction season: in rainy and lower temperature season，using emulsified asphalt can construct too，and prolong construction time，and shorten construction period，At last，improve construction condition and lessen environmental pollution. Water proof materials of emulsified asphalt point to the material that using emulsified asphalt mixed with aggregate，When mineral emulsifier is adulterated into emulsified asphalt，materials that emulsion mixes with filler are called as water proof paint of emulsified asphalt，while ，materials that emulsion mixes with aggregate and filler are called as mixture of emulsified asphalt. Proportion of water proof material of emulsified asphalt， mixing processing，and characteristics are carrying on studying，and the details are as follows:(1)Bituminous emulsificationQuality of emulsified asphalt affects very largely characteristics of water proof material of emulsified asphalt， Accordingly，in the article，the method of bituminous emulsification in the laboratory is elected，and we elect  multiple emulsifier and groped emulsified conditions，In these emulsified conditions，we emulsify emulsified asphalt of different concentration，and verify their characteristics to ensure qualification of bituminous emulsion characteristics, (2)Water proof paint of emulsified asphaltEmulsified asphalt，bin milk and cement are elected as raw material of water proof paint of emulsified asphalt，water proof paint are mixed by way adding material as follow: at first， adulterate emulsified asphalt，
