混凝土外加剂的应用是国家经委在“六五”期间重点推广项目之一。在混凝土及制品生产中应用外加剂,投资少,见效快;可带来明显的技术经济效益;能适应各种新工艺、新技术的发展,满足混凝土性能的改良,全面提高高强多功能混凝土工作性质的功效,推动混凝土技术进步。应用外加剂能节省水泥,节约能源,降低生产成本,提高台座、场地利用率。在浇筑过程中,它提高了混凝土拌合物的和易性,使成型能耗大、劳动条件差的干硬性混凝土逐步被塑性混凝土所代替,提高混凝土早期
The application of concrete admixtures is one of the key promotion projects of the State Economic Commission during the “6th Five-Year Plan” period. Application of admixtures in the production of concrete and products, with low investment and quick results; significant technical and economic benefits; ability to adapt to the development of various new processes and new technologies, to meet the improvement of concrete properties, and to improve the overall use of high-strength multi-purpose concrete The function of nature promotes the progress of concrete technology. Application of admixtures can save cement, save energy, reduce production costs, and increase the pedestal and site utilization. In the pouring process, it improves the workability of the concrete mixture, and the dry hard concrete with high energy consumption and poor working conditions is gradually replaced by the plastic concrete, improving the early stage of the concrete.
