外加剂的品种选择和合理应用是商品混凝土用好外加剂、满足用户对混凝土性能的要求的关键。本文提出在商品混凝土中应用外加剂,首先应满足技术可行性与经济合理性两个基本原则,其次在应用过程中,还应注意掺量、水灰比与掺量关系、掺加技术、配合比等因素的影响。文章还介绍了外加剂在福州商品混凝土站的应用情况。
The selection of additives and their reasonable application are the key to the use of good admixtures for commercial concrete to satisfy the user’s requirements for concrete performance. This paper proposes that the application of admixtures in commercial concrete should first meet the two basic principles of technical feasibility and economic rationality. Secondly, in the application process, attention should also be paid to the relationship between the amount of admixture, the ratio of water to cement and the amount of admixture, and the admixing technology. Than other factors. The article also introduced the application of admixtures at the Fuzhou commercial concrete station.
