Anti-Crak® HD

Reinforcing fibres

Manufacturer GAVAZZI TESSUTI TECNICI S.p.A. Socio Unico

Since their development and launch in 1970, Alkali Resistant glass fibers have been used in more than 120 countries for the reinforcement of cement and concrete products. They are best known for their use in factory-produced GRC elements (Glass fiber Reinforced Concrete), but the range of Anti-Crak® fibres has been developed to target the use of AR glass fibres in concrete and mortar applications for use in flooring and pavements, precast concrete, screeds and renders. With its total affinity to cementitious composites, high tensile strength and modulus of elasticity, glass fibers are an ideal reinforcement for concrete, already efficient at very early stages of the cracking process. Moreover, glass fiber density is similar to concrete, which allows a quick dispersion for very short mixing times, with minimum balling risk and exceptionally low influence on workability. Anti-Crak® HD fibers have been developed to satisfy different performance requirements, especially the prevention of plastic shrinkage cracking. Anti-Crak® HD product is a monofilament reinforcement representing more than 200 million filaments per kg. The high elastic modulus of Anti-Crak® HD fibers (72 GPa) and their excellent bond into a mineral matrix makes them an ideal reinforcement in plastic and hardened concrete. With a specific gravity similar to that of the aggregate they will neither float or sink in the mix, giving excellent dispersed reinforcement.
