Glass fibre Reinforced Concrete is a precast, self-supporting product with a thickness that depends on the project (1-1.5cm). It is composed of a base of cement with a resistance of 42.5N/mm2; quartz sand with a quartz (SiO2) content of over 96% by weight and with 100% of the grains being of a maximum width of 1.6mm; plus alkali-resistant glass fibre that forms filaments with a minimum zirconium content of 17.1% and with a tensile strength of 3500MPa.
Producto prefabricado autoportante de hormigón armado con fibra de vidrio, con grueso dependiente del proyecto ( 1-1,5 cm), compuesto por base de cemento de resistencia 42, 5 N/mm2 , arena de sílice y con contenido de Cuarzo (SiO2) superior al 96 % del peso de la arena y con un grueso máximo de 1,6mm del 100%, más fibra de vidrio resistente a los álcalis con forma de filamentos con contenido mínimo de Zirconio del 15% con una resistencia a tracción del filamento de 3.500 Mpa.
High tensile and flexure strength, due to the characteristics of the glass fibre. High impact resistance, due to the energy absorption of the glass fibres. Incombustible, due to the composition of its M-0 elements. High resistance to corrosive and atmospheric elements. Highly impermeable. Advantages: Transport Structure and foundations. Installation machinery. Fixings and assembly.
GRC is a technique for constructing precast concrete panels and parts that are reinforced with concentration of alkali-resistant (AR) glass fibre of between 3% and 5%.
This construction system means that the thickness of the precast panels can be reduced by up to 70%, whilst maintaining their high resistance.
It also means that: highly quality decorative parts can be made, the weight of structures on buildings can be reduced, building construction time can be accelerated by up to 30%, and resistance to earthquakes is increased significantly.
