《公路工程水泥混凝土外加剂与掺合料应用技术指南》编制介绍

Introduction About Compiling "Technical Guidelines for Applications of Chemical and Mineral Admixtures on Cement Concrete in Highway Engineering"

概略地介绍了2006年由交通部公路科学研究院编制完成、交通部交公便字[2006]02号文批准发布的公路行业推荐性标准《公路工程水泥混凝土外加剂与掺合料应用技术指南》编制的指导思想,外加剂应用中的共同技术要求、粉煤灰的应用技术等,希望起到对该指南的宣贯作用。

＂Technical Guidelines for Applications of Chemical and Mineral Admixtures on Cement Concrete in Highway Engineering＂ compiled by Research Institute of Highway of the Ministry of Communications is briefly introduced in this paper. The guideline emphasizes the use of chemical admixtures, such as water reducing admixture, air entraining admixture, set retarder, hardening accelerating admixture, anti-freezing admixture, pumping aid, water-repellent admixture, flash setting admixture, anti-corrosion admixture, flocculating agent; and mineral admixtures, such as fly ash, silicajume, slag, expanding admixture.
