由日本藤泽药品工业公司特药事业部新研制的“西贝咖岛”,是乙二醇醚系列的一种新型产品(正在申请专利),在具有降低干燥收缩作用的同时,能形成独特的气泡组织(即使极少量的空气,也对混凝土的抗冻性有良好影响),属于高性能降低干燥收缩的最新产品。该药物几乎不溶于水,但通过混合搅拌机的搅拌,很容易均匀分散。混凝土中添加该药物时,随着添加量的增加,长度变化明显减小(见图1)。图2
The “Xebeca Island” newly developed by the Fujisawa Pharmaceutical Industrial Company’s Special Pharmaceutical Division, Japan, is a new type of glycol ether series product (patent pending), which has the unique ability to reduce the drying shrinkage while also forming a unique product. The bubble structure (even a very small amount of air also has a good influence on the frost resistance of the concrete) is a new product with high performance in reducing drying shrinkage. The drug is almost insoluble in water, but it is easily dispersed evenly by stirring with a mixing stirrer. When the drug was added to the concrete, the length change significantly decreased with the addition of the drug (see Figure 1). figure 2
