Description FDN is a high range water reducer , commonly referred to as a superplasticizer. FDN is an anion surface active agent based on polyalkyaryl sulfonate. Having a strong dispersion effect on cement, it is a kind of highly effective, low air-entrained water-reducing agent with effective water reduction and low air-entrainment. FDN contains no added chloride. FDN meets the requirements of chemical admixture specifications for concrete: GB********7, GB*********3. Uses FDN superplasticizer can be applied to make flowable, strong or steam-curing concrete. The minimum working temperature can be as low as 0 C. In steam curing, concrete with superplasticizer has to strong enough before heating. The steam curing specification has to be pre-tested. It is particularly suitable to be base material for compound admixtures. FDN possesses the features of no retarding, no air-introducing, superplastic high water-reducing and strength enhancing. It has low alkali content, low sulfonate, and high purity. It can be widely used in different concretes with less dosage and easy to use. Advantages High water-reducing rate: FDN can reduce water more than *5%. It has features of superplasticizer, effectively increases concrete fluidity and reduces water penetration and segregation. Therefore, improves concrete placement and makes concrete easy to use and compacting. Strengthening: Given the same amount of cement and slump requirement, this product can increase the concrete stress by *****0%, ****0%, ****0% and ****0% on day 1, 3, 7, and *8 respectively. High applicability: It can be used with different variety of cement. It compatible with other admixtures. It can be used with expanding admixture, air entraining admixture as well as fly ash for supplement and catalystic purpose. Appropriate setting time: It has less effect on the initial and final setting time. The difference in setting time generally is less than 1 hour.
