What is macro fiber in concrete?

What macro fiber means in simple words Macro fiber in concrete means a larger fiber that is added to a concrete mix so the concrete can perform better after cracking starts. In today’s concrete industry, the term usually points to macro synthetic fibers, often made from polypropylene or other polyolefins. ACI 544.3R defines macrosynthetic fibers […]
What is micro fiber in concrete?

Micro fiber in concrete means very small, short fibers mixed throughout the concrete to improve its behavior, especially at the early stage. In current standards language, polymer micro fibres are typically defined as fibers with a diameter less than 0.30 mm. EN 14889-2 classifies them as Class I micro fibres, with Class Ia for monofilament […]
PVA Fiber for Concrete: A Distributor’s Guide to Specifications, Applications, and Sourcing

Distributors evaluating new concrete reinforcement products face a common challenge: most information about PVA fiber for concrete comes from academic research papers, not practical buying guides. That makes it hard to assess whether PVA fiber belongs in your product portfolio, what specifications matter, and how to source it with confidence. This guide closes that gap. […]
What is fibre reinforced concrete?

Fibre reinforced concrete, often shortened to FRC, is concrete made with cement, aggregates, and discrete reinforcing fibres mixed through the material. ACI defines fibre reinforced concrete as concrete made mainly of hydraulic cements, aggregates, and discrete reinforcing fibres. ASTM C1116 also treats it as concrete delivered with the ingredients uniformly mixed, and it classifies it […]
What Are the Disadvantages of Glass Fibre Reinforced Concrete?

Glass fibre reinforced concrete, often called GFRC, can solve many problems that normal concrete cannot. It can reduce panel weight, support thin sections, and create decorative shapes that are hard to make with ordinary reinforced concrete. At the same time, it is not a perfect material. Its disadvantages become very clear when it is used […]
What Is Brass-Coated Steel Fiber in Concrete and UHPC?

When people ask “What is brass-coated steel fiber?”, the simplest answer is this: it is a steel fiber with a thin layer of brass on its surface. Brass itself is a copper-zinc alloy. In concrete work, this product is often a small, straight, high-strength steel fiber used in UHPC, UHPFRC, and RPC rather than a […]
What is PP monofilament?

At Shandong Jianbang Chemical Fiber Co., Ltd., we explain PP monofilament in a very simple way: it is a single filament made from polypropylene. “PP” stands for polypropylene, which is a polyolefin polymer that can be melt-spun into fibers. “Monofilament” means one filament, not a bundle of many fine filaments. In general fiber processing, monofilaments […]
Is polypropylene fiber better than polyester fiber?

When buyers ask whether polypropylene fiber is better than polyester fiber, the most useful answer is this: polypropylene fiber is usually the better all-round choice for standard concrete work, but polyester fiber can be better in some specific cases. Polypropylene is lighter, melts at a much lower temperature, and has a strong track record in […]
What Is Fibrillated Polypropylene?

Fibrillated polypropylene is a polypropylene fiber made in a slit-film form that opens into many small branching fibrils. In concrete, it usually means a micro synthetic fiber used to reduce early cracking and improve cohesion in the fresh mix. The National Precast Concrete Association explains that fibrillated fibers are a slit-film fiber where parts of […]
What Is PP Embossed Macrofiber?

PP embossed macrofiber is a macro synthetic concrete fiber made from polypropylene, with a textured or embossed surface that helps the fiber grip the concrete better after cracks start to form. The term is common in product pages and sales materials, but the idea behind it is technical and standard-based. ACI defines macrosynthetic fibers as […]
