Fibra de formigó

Overview of concrete fiber

Fiber used in construction projects is a thin and long material with an aspect ratio of generally more than 100, and has a certain tensile strength (also called breaking strength), elastic modulus (també anomenat mòdul inicial) i allargament final (també anomenat elongació de ruptura). Les fibres utilitzades en projectes de construcció es refereixen principalment a materials de fibra discontinua de segment curt que es poden distribuir uniformement en el formigó i poden reforçar l'estructura del formigó..

Segons els diferents materials de fibra utilitzats, es poden dividir en: fibres naturals o fibres artificials; fibres orgàniques o fibres inorgàniques, etc. Concretament, es poden dividir en fibres orgàniques naturals (diverses fibres de cànem, fibres de pasta de fusta, fibres de closca de coco (anomenades col·lectivament fibres de cel·lulosa) i truges d'animals, etc.); fibres inorgàniques naturals (fibres d'amiant, wollastonita en forma d'agulla, etc.), fibres orgàniques artificials (també anomenades fibres sintètiques: fibres de polipropilè, fibres de poliacrilonitril, fibres d'alcohol polivinílic, fibres de polièster, fibres de poliamida, ultra-high molecular weight polyethylene fibers, etc.), and artificial inorganic fibers (metal fibers, glass fibers, basalt fibers, fibres de llana mineral, i fibres de carboni, etc.). Segons els diferents mòduls elàstics de la fibra utilitzada, és a dir, si el mòdul elàstic de la fibra és superior o inferior al mòdul elàstic de la matriu amb la qual es barreja, es pot dividir en fibra de mòdul elàstic alt i fibra de mòdul elàstic baix; segons els diferents materials de la matriu amb què es barreja, es pot dividir en: fibra per a formigó de ciment, fibra per a morter (pasta de ciment), fibra per a formigó asfàltic, etc.

El formigó de fibra es pot considerar com un formigó compost amb una certa quantitat de curt, uniformement dispersos, i fibres discontínues afegides al formigó normal. La combinació de fibra i matriu de formigó millora les debilitats inherents del formigó i té un impacte multifacètic en el rendiment del formigó.. The improvement of the crack resistance and durability of fiber concrete is of great significance to the construction of high-quality, beautiful and durable projects.

The role of fiber in concrete

Including fiber to concrete can increase the strength and split resistance of the material, and at the same time has a specific impact on the strength and rigidity of concrete

Boost the tensile toughness of concrete

The stamina of concrete generally comes from the cement and accumulation in the mixture. The tensile strength of concrete is extremely reduced. Adding a proper amount of fiber can make concrete have better tensile toughness, thus boosting the total strength of the concrete structure.

Enhance the sturdiness of concrete

The fiber in concrete can enhance the residential or commercial properties of microcracks in concrete, minimize the water leaks in the structure and air permeability in concrete, boost the frost resistance and sturdiness of concrete, and thus extend the service life of concrete.
Boost the influence performance of concrete.

After adding fiber, the energy absorption capability of concrete can be enhanced, therefore improving the influence performance of concrete and minimizing the degree of stamina reduction.

Types of fibers

Steel fiber

Metal fiber is a standard fiber contributed to concrete, such as steel fiber, aluminum alloy fiber, and so on. They have high toughness and large ductility. After adding them to concrete, they can enhance the seismic resistance and crack resistance of concrete, yet steel fiber is prone to rust.

Synthetic fiber

Artificial fiber products have good deterioration resistance and alkali resistance, mainly polypropylene fiber and nylon fiber, and so on. The addition of these fibers can efficiently enhance the fracture resistance and bending and tensile resistance of concrete, thus improving the overall performance of concrete.
Glass fiber

Glass fiber is cheap and is included big amounts. It is made use of greater than iron cable. It can boost the fracture resistance and impermeability of concrete and is challenging to corrosion.

The result of fiber on concrete toughness

The impact of fiber on concrete stamina generally consists of the following aspects:

Fiber type and size

Fibers of different types and sizes have various impacts on the stamina of concrete. Generally speaking, the longer the fiber length, the greater the result on the stamina of concrete.

Fiber enhancement

The quantity of fiber included likewise has a wonderful impact on the strength of concrete. Inadequate will certainly have virtually no result, while too much might cause the strength of concrete to lower.

Fiber circulation

Irregular circulation of fibers might trigger the strength of concrete to reduce, so when adding fibers, it is needed to pay attention to the full mixing of concrete and fibers.

Applications of Concrete Fiber

Building and construction: Used in slabs, paviments, bridge decks, and precast elements to raise durability and decrease upkeep.
Roadways and Freeways: Improves toughness and decreases the threat of fractures and rutting.

Industrial Floors: Dóna resistència a tones pesades i influeix en magatzems i instal·lacions de fabricació.

Reparació: Ideal per a superposicions i serveis de reparació on es necessita un ràpid augment de resistència i molt poc temps d'inactivitat.

Projectes Residencials: Fes ús de les calçada, zones de pati, i passarel·les per aturar la fractura i millorar l'atractiu visual.

FAQs of Concrete Fiber

Q: How do fibers improve concrete?

A: Fibers act as internal reinforcement, bridging micro-cracks and improving the overall mechanical properties of the concrete.

Q: Are concrete fibers costly?

A: The cost differs depending upon the sort of fiber and quantity required. Typically, while fibers might contribute to initial prices, they can decrease long-term expenditures via enhanced toughness and fewer repair work.

Q: Can concrete fibers change rebar?

A: While fibers boost several aspects of concrete performance, they typically do not completely change traditional rebar in important load-bearing frameworks. Nevertheless, they can often decrease the amount of rebar needed.

Q: Exist any kind of environmental interest in using concrete fibers?

A: The ecological impact depends on the type of fiber made use of. Synthetic fibers are stemmed from petrochemicals, whereas all-natural fibers are biodegradable but may have restricted performance. Sustainability factors to consider ought to direct the selection of fiber type.

Q: Just how do I mix concrete fibers?

A: Fibers are normally added directly to the concrete mixer at the specified dose rate. Proper mixing guarantees uniform distribution throughout the concrete. Maker guidelines should constantly be followed.
