我们在混凝土中进行了掺加木素铁铬盐的探讨性试验。木素铁铬盐对混凝土减水效果明显,混凝土的一般性能有不同程度的改善,对钢筋没有锈蚀作用。木素铁铬盐的货源很广,成本便宜,适宜在混凝土施工中大量采用。一、木素铁铬盐的一般性能及使用方法木素铁铬盐是吉林省开山屯造纸厂从废液中回收提练的一种棕色粉末,可溶于水,亲水性能好,具有良好的表面活性,可作混凝土减水剂和增强剂。在混凝土中使用的方法有两种:1.湿掺法:将木素铁铬盐按需用量加入 We conducted an exploratory experiment of adding lignin iron chromium salt in concrete. The lignin iron and chromium salt has obvious water reducing effect on the concrete, and the general performance of the concrete is improved to varying degrees, and there is no rust effect on the steel bar. The supply of lignin, iron and chromium salt is very wide, and the cost is low. It is suitable for large-scale adoption in concrete construction. I. General properties and methods of use of lignin iron chromium salt Lignin iron chromium salt is a brown powder recovered and recovered from the waste liquor by Kaishantun Paper Mill in Jilin Province. It is soluble in water and has good hydrophilicity and good properties. The surface activity can be used as concrete water reducer and enhancer. There are two methods used in concrete: 1. Wet incorporation method: Add the amount of lignin iron and chromium salt as required
