水利工程在国家经济建设中起着重要的作用,水利工程中防渗工作是水利工程建设中的重要部分,水利工程防渗施工质量直接影响工程的整体质量及后期运行水平,也关系到人民群众的生命和财产安全。防渗也是提高水利工程性能的最重要的措施之一,而且防渗材料也是多种多样。本论述通过使用酒石酸、硅酸钠粉等制备新型防渗剂,并研究其物理力学性能、抗渗压力等性能。结果表明:随着酒石酸含量的增加,防渗剂的物理力学性能和抗渗性能均有了显著提高,酒石酸占胶凝材料质量的2%时,终凝时间为26 h,28天抗压强度达到54.85 MPa,28 d渗压比达到375%,湿基面粘结强度达到3.6 MPa。
Water conservancy projects play an important role in the national economic construction. Seepage control works in water conservancy projects are an important part of water conservancy projects. The quality of seepage control constructions of water conservancy projects has a direct impact on the overall quality and the later operation level of the project, as well as the masses Life and property safety. Anti-seepage is also one of the most important measures to improve the performance of hydraulic engineering, and impermeable materials are also varied. In this dissertation, tartaric acid and sodium silicate powder were used to prepare new type of anti-penetration agent, and their physical and mechanical properties, anti-seepage pressure and other properties were studied. The results showed that with the increase of tartaric acid content, the physical and mechanical properties and impermeability of the anti-penetration agent were significantly increased. The tartaric acid accounted for 26% of the total mass of the cementitious material at 26 h. The compressive strength Reached 54.85 MPa, the seepage pressure ratio reached 375% on 28 days and the wet-based bond strength reached 3.6 MPa.
