糖蜜外加剂在国内水利工程中应用较广。近几年来,我省水利工程中也逐步推广使用,取得了良好的技术经济效果。糖蜜外加剂是一种减水缓凝剂,对于要求混凝土缓凝、增强的工程是比较理想的外加剂,但对提高混凝土抗渗性能不明显。本文是采用本省的原材料进行试验而写成的,可供我省中小型水利水电工程使用糖蜜外加剂时参考。 Molasses additives in the domestic water conservancy project is widely used. In recent years, water conservancy projects in our province have also been gradually promoted, and achieved good technical and economic results. Molasses admixture is a kind of water-reducing retarder, which is an ideal admixture for delaying and enhancing concrete, but it is not obvious to improve impermeability of concrete. This article is written using the province’s raw materials for testing, for our province small and medium-sized water conservancy and hydropower project when using molasses admixture reference.
