What Is Shotcrete? Dry-Mix, Wet-Mix, Fiber Reinforcement, and Quality Control
Why Shotcrete Is More Than Sprayed Concrete Shotcrete is often described as concrete sprayed onto a surface. That explanation is correct, but incomplete. The process delivers concrete or mortar through a hose and projects it pneumatically at high velocity. Impact against the receiving surface places and compacts the material at the same time. This allows […]
Micro Synthetic Fiber for Concrete: The Distributor’s Guide to Shrinkage Control, Specs & Product Selection
Micro synthetic fiber is the most widely used fiber type in concrete worldwide. It appears in residential driveways, commercial sidewalks, shotcrete, stucco, and repair mortar. For distributors, this product offers a low-cost entry point into the concrete fiber market with a broad customer base and straightforward specifications. This guide covers what distributors need to know […]
Steel Fiber Dosage In Concrete: How Volume Content Affects Flow, Distribution, And Crack Control
Why Steel Fiber Dosage Matters In Concrete Concrete is strong under compression. This is why it is used in floors, tunnels, bridges, precast parts, pavements, and many other structures. But concrete has one clear weakness. It does not perform well under tension. Once cracks form, the material can lose load capacity fast. Steel fiber helps […]
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 […]
