Polycarboxylate®Polyfume-23 Silica fume in powder

Description

Polycarboxylate®Polyfume–23 is an ultrafine and micrometric silica from plants producing silicium.
Introduced in the concrete with hydraulic binder, Polycarboxylate®Polyfume–23 behaves like a pozzolan.
Its fineness procures a huge reactivity with cement.
Polycarboxylate®Polyfume–23 improves the cohesion and compacity of concrete. It avoids phenomenes of segregation.

Areas of Application

Polycarboxylate®Polyfume-23is recommended for High Performance and low carbon concrete mixes where
high rheological and mechanical performance are
sought and required

▪All types of cement particularly blended cements
▪High and Ultra-High-Performance Concrete
▪Concrete of humid, plastic or fluid consistency (SCC)
▪Ready-Mix, Precast and Jobsite concretes
▪Specific Ready-mix and Jobsite concretes
▪Concrete with extended workability retention
▪High durable and ultrahigh strength concrete
▪Improved internal cohesion
▪Water retention and increased density when set
▪Improved pumping properties
▪Improved durability
▪Improved water tightness
▪Improved surface finish
▪Increased resistance to abrasion
▪Reduced chloride diffusion
▪Improved ultimate strength.

Benefits

Polycarboxylate® Polyfume-23 contains extremely fine (0.1 µm) 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.

▪Working with Polycarboxylate® Polyfume-23
▪Improves long term strengths of concrete
▪facilitates the pumping of concrete, even with low rate of cement,
▪improves durability of concrete inaggressive environment
▪improves freeze-thaw resistance
