Overview of High-strength basalt chopped fiber for concrete reinforcement ex-factory

For high-impact resistance, we offer Steel Fibers, an ideal replacement for welded wire mesh in industrial floors and pre-cast elements. We also provide specialized Structural Synthetic Fibers that offer high tensile strength for demanding applications. These fibers are uniformly dispersed throughout the concrete mix, creating a multi-dimensional reinforcement network that traditional methods cannot achieve. This integrated approach simplifies construction, accelerates placement, and enhances the overall integrity and longevity of the concrete, providing a modern answer to age-old cracking and durability challenges.

Features of High-strength basalt chopped fiber for concrete reinforcement ex-factory

1. Superior Crack Control and Enhanced Durability:

The primary feature of our fibers is their ability to bridge both micro-cracks that form during the plastic state and larger cracks in hardened concrete. This three-dimensional dispersion creates a more cohesive matrix that resists crack propagation. The direct benefit is a significant reduction in both plastic shrinkage cracking and long-term crack width. This leads to a much more durable concrete with lower permeability, which in turn enhances resistance to water ingress, freeze-thaw damage, and corrosion of any embedded steel. The result is a structure with a longer service life and reduced maintenance costs.

2. Increased Impact and Abrasion Resistance:

Fibers, particularly steel and robust synthetic macro fibers, dramatically improve the concrete’s toughness and post-crack performance. They absorb and distribute energy upon impact or loading. This feature provides the benefit of a more resilient surface that is less prone to spalling, chipping, and abrasion under heavy traffic or mechanical wear. This is a critical advantage for industrial floors, warehouse pavements, and infrastructure projects, leading to a harder-wearing surface that maintains its integrity over time.

3. Construction Efficiency and Cost Savings:

A key feature of using fiber reinforcement is the elimination of welded wire mesh (WWF) in many applications. This provides immense on-site benefits: it simplifies placement, as there is no mesh to be set up or potentially displaced, and it accelerates the entire construction process. By removing a labor-intensive step, projects see reduced labor costs and faster project timelines. The uniform distribution of fibers also ensures consistent reinforcement throughout the entire concrete section, unlike mesh, which can be improperly placed, leading to more reliable and predictable performance.

Specifications of High-strength basalt chopped fiber for concrete reinforcement ex-factory

Our high-strength basalt chopped fiber strengthens concrete. We supply it directly from our factory. This fiber is made from natural basalt rock. It gets cut into short pieces for mixing into concrete. The chopped fibers are very strong. They help concrete resist cracking better. Concrete gets tougher with this fiber added.

You can get different fiber lengths. Common lengths are 12mm and 24mm. The fiber diameter is very fine, around 17 microns. This fine size lets the fibers spread well in the mix. The specific gravity of the fiber is about 2.65 g/cm³. It is denser than water. The material itself is naturally resistant to alkalis. This is important because concrete is alkaline. The fiber won’t break down easily in the concrete environment.

The tensile strength of the fiber is very high. It is over 3000 MPa. This means the fibers themselves are incredibly strong. They have a high elastic modulus too. This helps the concrete stay stiff under load. Adding these fibers improves the concrete’s performance. It reduces early plastic shrinkage cracks. It controls drying shrinkage cracks later on. The concrete becomes more impact resistant. It handles freeze-thaw cycles better. Abrasion resistance also improves.

We pack the chopped fiber in strong polypropylene bags. Standard bag weights are 25 kilograms. Store the bags in a dry place indoors. Keep the bags off the ground. Moisture can be a problem. The fiber is easy to handle. Add it directly into the concrete mixer during batching. Follow the recommended dosage rates. The typical dosage is between 1 and 3 kilograms per cubic meter of concrete. Mixing time might need a slight increase. This ensures good fiber dispersion throughout the concrete. Proper dispersion is key for the fiber to work well.

Applications of High-strength basalt chopped fiber for concrete reinforcement ex-factory

Our basalt chopped fiber strengthens concrete. It comes straight from our factory. This fiber is made from natural volcanic rock. It is very strong and lasts a long time. People use it to make concrete better. It helps stop cracks. It also makes concrete tougher.

Builders add this fiber to concrete mixes. It mixes in easily. It spreads out well inside the concrete. This fiber adds tensile strength. Concrete is weak when pulled apart. The fiber holds it together better. It stops cracks from spreading. This makes slabs and foundations stronger.

This fiber works well for industrial floors. These floors get heavy use. Trucks drive on them. Heavy things are dropped. The fiber helps the floor resist damage. It reduces cracking and chipping. This means floors last longer. They need less fixing later.

Tunnels and bridges need strong concrete. These structures face harsh conditions. Water, salt, and chemicals attack them. Basalt fiber does not rust. Steel reinforcement can rust. Rust causes big problems. Basalt fiber avoids this issue. It helps concrete resist chemical attack.

Repairing old concrete is easier with basalt fiber. Workers add it to repair mortars. It makes the patch bond better. It also makes the patch stronger. This stops new cracks from forming. It gives a lasting fix.

Precast concrete parts benefit too. Things like pipes, panels, and blocks are made ahead of time. Adding basalt fiber makes them tougher. They handle shipping and installation better. They resist damage during use. This fiber is a smart choice for many concrete jobs.

5 FAQs of High-strength basalt chopped fiber for concrete reinforcement ex-factory

What is basalt chopped fiber? It is a reinforcement material made from natural basalt rock. The rock is melted and stretched into thin fibers. These fibers are then chopped into short lengths. We sell these chopped fibers for adding directly into concrete mixes.

Why use basalt fiber instead of steel or glass fiber? Basalt fiber offers several benefits. It is much stronger than glass fiber. It does not rust like steel can. It is chemically very stable. This means it resists damage from salts or chemicals often found near concrete. It is also lighter than steel.

How does basalt fiber make concrete better? Adding basalt chopped fiber improves the concrete’s toughness. It helps control cracking as the concrete dries and hardens. It makes the concrete more resistant to impact forces. It also improves the concrete’s ability to withstand wear and tear over time. This leads to longer-lasting structures.

How much fiber do I add to the concrete mix? The amount needed depends on the specific project. Common dosages range from 1 kilogram to 5 kilograms per cubic meter of concrete. We can provide guidance based on your application. It is important to mix the fibers thoroughly into the concrete for even distribution. Follow standard mixing procedures.

How is the fiber packaged and stored? We supply our basalt chopped fiber in tough, sealed plastic bags. Standard bag sizes are 25 kilograms. Store the bags in a dry, covered area. Keep them away from direct sunlight and moisture before use. The bags are designed to protect the fibers during transport and storage.
