Introduction: Point-HF is a new type of admixture compounded by inorganic function material and organic polymer function material. It has various functions such as high water reducing, reinforcing, plasticizing, micro inflation and low bleeding. Being mixed with cement or concrete, it can compensate the shrinkage occurring in different periods of hardened cement paste or concrete. It can not only significantly increase the fluidity of grouting compound in conditions of lower water/cement ratio, but also can effectively settle the contradiction between high fluidity and anti-separation of concrete mixing system with multi-phase, multi-composition and non even.

Features:

The product has functions of high water reducing and reinforcing with water reduction rate of more than 25%. The off-machine fluidity cone time of grouting compound prepared with 13% dosage Point-HF is 14-22 seconds, which indicates that the grouting compound has high fluidity and great groutability. Even in case of irregular and complicate structure, the paste can also freely fill into each part and self compact.

Grouting compound with Point-HF can significantly decrease the bleeding rate. Due to the functional organic polymer material is used, on the premise of ensuring high fluidity of paste, it can properly increase the viscosity to effectively avoid sedimentation and separation, and prevent water move into paste top and cause grouting defects. The bleeding rate of grouting compound with 13% Point-HF is nearly zero.

Paste mixture with Point-HF can produce proper micro inflation in different stage of hydration hardening to compensate the plasticizing shrinkage, dry shrinkage and self volume shrinkage. Paste with Point-HF has no shrinkage in early stage, which ensures stable volume of paste after hardening.

It has proper set retarding and fluidity retaining. By using the product, grouting construction time can be ensured and the set retarding retaining composition rate can be adjusted depending on seasons, therefore, it is suitable for constructions in different seasons.

Safety properties: Non-toxic, non-irritant, non-radioactive, nonflammable, non-explosive, non-dangerous, and no corrosive to steel bar.
