The addition of READYMESH MR-200 improves the mechanical properties of the conglomerate in terms of ductility, mechanical performance, energy absorption, toughness, fatigue and wear resistance. They also help control the plastic shrinkage in the conglomerate (cracking) and reduce or eliminate the need for conventional reinforcements such as electro-welded meshes.


Variable according to the type of work to be carried out and/or performance to be achieved.

Use fields

The READYMESH MR-200 micro-fibres are widely used as main and unique reinforcement for low thickness structural mortars, sprayed plasters and concretes (shotcrete, spritz-beton), precast concrete products.

Use method

READYMESH MR-200 fibres will be added to the conglomerate during mixing in a gradual manner, avoiding immediate introduction of the whole quantity of fibre required. Having introduced the READYMESH MR-200 fibre, continue with mixing for at least another 3 minutes so that the distribution is uniform in the mixture.
