随着建筑施工技术的发展,开发高强泵送商品混凝土已成为迫切需要。1989年由上海市建筑工程管理局向上海市建筑工程材料公司下达了预拌高强泵送混凝上(高强泵送商品混凝土)科研项目,经试验研究和工程试点于1990年10月通过技术鉴定,该科研成果已成功地应用于南浦大桥等工程。1 特点本工法突破了传统的商品混凝土制备工艺,既达到 C40以上强度等级,又满足了泵送施工的要
With the development of building construction technology, the development of high-strength pumped commercial concrete has become an urgent need. In 1989, the Shanghai Municipal Construction Engineering Administration issued a premix high-strength pumping coagulation (high-strength pumped commodity concrete) scientific research project to Shanghai Construction Engineering Materials Co., Ltd., which passed technical appraisal in October 1990 through experimental research and engineering pilot projects. The scientific research results have been successfully applied to the Nanpu Bridge and other projects. 1 Features This engineering method breaks through the traditional commercial concrete preparation process, achieving strength levels above C40 and meeting the requirements for pumping construction.
