concrete additive of a new generation in powder form, based on Sika silicafume® technology
📄Product Description:
Sika Fume® -HR is a concrete additive of a new generation in powder form, based on Sika silicafume® technology.
Uses:
Sika Fume® -HR is used in structural concrete, precast concrete and other elds of concrete constructions where high demands are imposed on the quality of fresh and hardened concrete.
Advantages:
Sika Fume® -HR contains extremely ne (0.1 m) latently reactive silicon dioxide The presence of this substance imparts greatly improved internal cohesion and water retention. The concrete becomes extremely soft and pumping properties are substantially improved. In the set concrete the latently reactive silica fume forms a chemical bond with the free lime.
The additional crystal formation produces a significantly more dense set cement matrix.
When additionally using Sikament® super plasticizer, the concrete will show the following properties:
Excellent workability.
Increased durability.
High early strengths.
Increased ultimate strengths.
Increased resistance to abrasion.
Highly increased water tightness.
Highly increased gas tightness.
Highly reduced chloride diffusion.
Chloride free - does not attack any reinforcement.
