UHPC Brass Coated Fibres
UHPC Brass Coated Fibres
Shaktiman® Brass Coated Micro Steel Fibres (MSMF 2013) is a new and special class of brass coated steel fibres that have been developed in recent years for its exceptional properties of strength and durability. Due to high density of steel fibres in concrete mix, these are ideally used in Ultra High Performance Concrete. These high performing steel fibres can be utilized in structural rehabilitation and accelerated bridge construction, Roads, Tunnels etc., in addition to several other
high performance and special concrete applications.

Strength in UHPC Application
UHPC has a compressive strength 10 times that of traditional concrete. Compressive strength is the ability of a material to resist bending under a load (or in compression). While traditional concrete has a tensile strength of 400 – 700 psi, UHPC has a tensile strength of about 1400 psi.
Durability
While the strength of Brass Coated Micro Steel Fibres is impressive, it’s durability further exceeds expectations. Durability is measured by how the material performs under extreme conditions. Due to the presence of high density of steel fibres, UHPC has properties similar to hard rock when combined with Brass Coated Micro Steel Fibres Reinforcement.
Abrasion resistance is determined by measuring the amount of concrete abraded off a surface by a rotating cutter in a given time period. Brass Coated Micro Steel Fibres Reinforced Concrete demonstrates excellent abrasion resistance, nearly twice as resistant as normal concrete.
UHPC thus fills a critical gap between structural steel and concrete and opens new areas of applications in the design and construction of structures.
Our Brass-Coated Micro Steel Fibres are ultra-fine steel fibres with a brass or copper coating. These are specifically intended for applications with tight concrete cover, thin elements, superior bonding, or where micro-crack suppression (e.g. plastic shrinkage, thermal stress) matters. The brass coating may assist in corrosion protection relative to uncoated steel under certain conditions. These micro-diameter fibers are ideal for overlays, thin slabs and precast elements where traditional fibers may be too bulky or visible.
Key Features
Micro-Crack Bridging
Controls shrinkage cracking, early thermal cracking, and micro fissures before they grow.
High Tensile Strength & Fine Geometry
Being extra fine, the tensile strength of the fiber is much higher than regular steel fiber. Fine diameter lets them distribute densely; brass coating helps bonding and possibly protection.
Minimal Impact on Workability
Because of small size and volume, mixes remain workable without large voids or entanglement.
Ideal in Thin / High-Precision Elements
Precast components, RPC covers, overlays where the concrete cross-section is limited. They can also be used in joint sealing polymers in pavements, roads, bridges, etc.
