GRC concrete (also known as GFRC fiber-concrete or fibre-concrete) is an architectural decorative composite enriched with alkali-resistant fiber glass. GRC abbreviation stands for the first letters of English expression “Glassfibre Reinforced Concrete”. GRC is one of the most advanced materials currently used in the construction industry. The differences between GRC and the traditional concrete relate to the components and manufacturing technology. The basic ingredients of GRC are, as in the case of ordinary concrete, water, cement and sand. These are, of course, high-quality materials, and the sand must also have an adequately small and regular structure. The additives that make the difference, are the above mentioned glass fibers, as well as dyes and chemicals that also affect the resistance of the fiber-concrete. For this reason, its biggest advantages are durability, very high resistance to stress and changing weather conditions, as well as resistance to bending, compression and tension. GRC concrete is light, and it can be applied on a particular surface either in the form of finished plates, and sprayed.. The glass fibers make it is also extremely elastic and easy to handle and mold. Thanks to the above properties GRC concrete is increasingly common solution used in the architecture, art and design. It is worth remembering that the most reputable manufacturers of GRFC composites produce it based on their own, unique recipes, they also apply proprietary production technologies.
