Technological development and more and more advanced architectural designs lead to the creation and development of modern and constantly improving building materials. The same is true for concrete, where years of work have led to the creation of a top-quality material capable of meeting the needs of even the most demanding designs and users.
Concrete with structural reinforcement – otherwise called fibre concrete – is a material containing short, discrete and randomly distributed fibres. These can come from a variety of materials, the most common ones are steel, glass, synthetic and natural fibres – each of them gives the concrete different properties. In addition, the nature of fibre concrete varies with the geometry, distribution of the elements and the density of the prepared mixture.
In addition to the use of special fibres in fibre concrete, the other components are not substantially different from those used in ordinary concrete. The same cements and aggregates as for conventional concretes can be used for fibre concrete.
The advantage of fibre concrete against ordinary concrete
We owe the idea of using fibres in concrete mixes to heavy industry, among others. A classic concrete slab reinforced with a mesh has proved to be a material that does not show flexibility and is susceptible to damage over the years, shown by numerous cracks appearing on it. In the environment of engineers and scientists, questions arose as to whether it is possible to produce a material with properties similar to ordinary concrete, but with greater flexibility. The use of fibres gave birth to many new possibilities, and fibre concrete itself, thanks to its properties, is ahead of its predecessor. Compared to classic concrete, fibre concrete:
- increases the material strength against the stretching of the composite system;
- reduces spaces filled with air in classic concrete;
- acts as a crack stopper thanks to the addition of small, dispersed fibres;
- has greater resistance to abrasion, impacts and cracks
Regardless of the type of fibres used, each of them is randomly distributed in the whole mix, which is why increased strength is felt throughout the whole surface, not concentrated in a specific area. Thanks to this, any damage is neutralized before actual serious damage is caused.
Fibre concrete – save time and money
In addition to the above-mentioned strength, fibre concrete also offers a number of financial benefits:
- reduced plate thickness – saves space and expenses on the amount of material needed;
- simplified construction – accelerates the construction process;
- easy and quick maintenance
