本文研究了葡萄糖酸钠的制备方法,探讨了反应条件对转化率的影响,并进行了混凝土性能测试。研究表明,催化氧化法制备的液体葡萄糖酸钠与生物发酵法制备的产品性能相当,水泥适应性良好,对混凝土具有较好的缓凝作用和辅助塑化效果,还可使混凝土的后期强度稍有提高。 In this paper, the preparation of sodium gluconate was studied, the effect of reaction conditions on the conversion was discussed, and the performance of concrete was tested. The results show that the liquid sodium gluconate prepared by catalytic oxidation is equivalent to the product prepared by bio-fermentation, the cement has good adaptability, good retarding effect and auxiliary plasticizing effect on concrete, and the post-curing strength of concrete Improve.
