摘要
模拟水泥存放环境,研究了链烷醇胺类助磨剂对存放60d后水泥力学性能及粉体性能(如颗粒形貌和休止角)的影响。结果表明,水泥长期储存后抗压强度降低,而掺入链烷醇胺类助磨剂的水泥的强度降低幅度更大;长期储存后水泥颗粒表面出现了明显的凝胶状物质,休止角也明显增大。
Effects of alkanolamines grinding aids on the mechanical properties and powder properties, such as particle morphology and angle of reposes, of cement that storage 60 days in analog storage conditions were investigated. The results showed that the compressive strength of ordinary cement would decrease, and the addition of alkanolamines grinding aids caused much greater decreasing amplitude. After long-term storage, there appeared gel materials on cement particle surface, and the angle of reposes also increased evidently.
