摘要
硫酸盐侵蚀是影响水泥混凝土结构耐久性的重要因素之一,提高水泥的抗侵蚀性能对工程建设具有深远意义。通过对国内外对水泥抗硫酸盐性能的研究进展,归纳和比较了国内外抗硫酸盐水泥研究中硫酸盐对水泥基的侵蚀破坏机理、抗侵蚀程度的检验指标和评定方法、硫酸盐对水泥基的不同破坏类型及其影响因素以及改善并提高水泥基抗侵蚀性能的措施等方面研究的共性及差异性。在此基础上,提出了发展绿色环保的新型抗硫酸盐水泥研究前景和思路。
Sulfate erosion is one of the most important factors that affects the durability of cement concrete structure.It is of further significance to strengthen the sulfate resistance ability of cement-based materials.This paper has described the progress on the sulfate resistance of cement at home and abroad.Moreover,comparative study between domestic and foreign sulfate-resistant cement-based materials in the aspects of erosion mechanism,erosion test index and its evaluation methods is carried out.Meanwhile,the different types of erosion and its influence factors are also investigated.Based on these similarities and differences,this paper not only proposes the measures of improving the sulfate resistance properties of cement but also analyzes the issues about research results and existing problems in the sulfate-resistant cement.Finally,the prospect and idea of developing new type of green sulfate-resistant cement are put forward.
