摘　　要：抗渗混凝土是一种价格低廉,体积稳定性好,耐久性好的一种工程复合材料,在研究在桥梁、大坝等建筑工程上应用具有重要意义。根据目前研究,加入适量的矿物掺合料可以有效提高混凝土的抗渗性能,为抗渗混凝土的应用发挥更好的优势。文中从粉煤灰、硅灰、矿渣、纤维对其改善渗透效果进行总结,为抗渗混凝土在重点工程领域的应用提供有效参考。The presence of oil sludge exacerbates the pollution and erosion of new crude oil,bringing safety risks to the use of crude oil.Therefore,effective treatment of oil sludge is necessary.For the oil sludge at the bottom of the tank,various treatment methods can be used.In this paper,microwave pyrolysis was chosen,and the following work was carried out as follows:starting from the various hazards of the oil sludge at the bottom of the tank,a detailed summary and analysis were conducted on its basic characteristics and purification index.The current research status and existing problems of the oil sludge system at the bottom of the tank at home and abroad were also summarized and studied in detail.Based on the overall design requirements and simulation calculations of microwave pyrolysis technology for tank bottom sludge,a set of microwave pyrolysis technology for tank sludge suitable for modern Chinese refineries has been obtained.In the microwave pyrolysis of sludge,an important problem was the size of the waveguide and the size of the microwave cavity.According to the physical parameters of sludge and other influencing factors,a microwave pyrolysis mode suitable for sludge should be determined.A model was established by using COMSOL software,and the microwave pyrolysis process of oil sludge was simulated with this model.The optimal microwave frequency and output power were selected based on simulation calculation.
