混凝土预制构件生产中,养护工艺是重要环节,它不仅对产品质量有较大影响,而且是加速模板周转提高劳动生产率的关键。我所在上海市混凝土制品二厂的协助下,开展了陶粒混凝土快速蒸养的试验研究。试验结合双钢筋混凝土施工工艺,集中对蒸养用外加剂的选择和先热烫后蒸养的养护技术进行研究,并初步探讨了硫酸钠在快速蒸养中的作用。
In the production of prefabricated concrete components, the maintenance process is an important part. It not only has a great influence on product quality, but also is the key to accelerating the turnover of the template and increasing the labor productivity. Under the assistance of Shanghai No. 2 Concrete Plant, I conducted experimental research on rapid steam curing of ceramsite concrete. The test combined with the double-reinforced concrete construction process, focused on the selection of steaming additives and the curing technology of steaming after the first blanching, and preliminary discussed the role of sodium sulfate in rapid steaming.
