木质素减水剂除具有原料来源广、价格低廉、公害小等特点外,还具有引起世界各国专家所重视的使混凝土具有较好的抗冻性能和耐久性。因此木质素减水剂在一些国家发展较快。1980年在伦敦召开的国际会议上,介绍了美国产的以木质素磺酸盐为主成分的减水剂约占80％。根据1979年日本来华座谈时日曹公司介绍,该公司生产的减水剂量占日本生产的减水剂总量的35％,而木质素减水剂又占该公司总量的70％,多元醇类减水剂20～25％。总之,国际上目前应用的减水剂用量最大的是木质素减水剂。 In addition to the characteristics of a wide range of sources of raw materials, low prices, and low pollution, lignin water-reducing agents have also attracted the attention of experts from all over the world to make concrete have better frost resistance and durability. Therefore, lignin water reducing agents have developed rapidly in some countries. At an international conference held in London in 1980, it was introduced that about 80% of American-made water-reducing agents based on lignosulfonates accounted for about 80%. According to the company’s discussion in Japan in 1979, Cao Company introduced that the company’s water-reducing dose accounts for 35% of the total amount of water-reducing agent produced in Japan, and lignin water-reducing agent accounts for 70% of the total amount of the company. Polyhydrin superplasticizer 20 to 25%. In short, the largest amount of superplasticizer currently used in the world is the lignin superplasticizer.
