CAPSULES AS A PREVENTION OF FIBRE CLUSTERS IN CONCRETE

K. Pospíšil, J. Stryk, R. Matula 

Homogenous concrete mixture without aggregate pockets and fibre clusters is a presumption for appropriate properties of concrete element or structure. There are technological measures how to achieve homogenously looking mixture from aggregate point of view, but fibres are still predisposed for clusters forming. The paper evaluates originally designed and protected within European patent treatment of fibre, based on capsules containing individual rolled fibre which can be admixed into a concrete mixture and set up homogenously in its whole volume within the mixing process.
