12mm fibrillated polypropylene micro-fibre for screeds and concrete

Code: RDM.0246

Components: 1

Appearance: Fibers

READYMESH PW-120 is an auxiliary fibrillated polypropylene micro-fibre, with a length of 12 mm, suitable for adding concrete in general. The addition of READYMESH PW-120 to the mixture allows for preventing the phenomenon of cracking from plastic shrinkage of the concrete, as well as having positive effects as regards the ductility of the mixture, the resistance to freezing/thawing, the shock resistance and overall watertightness.

Variable according to the type of work to be carried out (screeds, plasters, mortars), on average from 0.6 to 1.5 kg per cubic metre of cement or hydraulic lime based conglomerate.

Use fields

Subbase screeds(even with radiant systems), small thickness small prefabrication casts, concrete floors, ballasts in cement mix and concrete structures in general, even in combination with traditional metal reinforcement.

Use method

Add the fibres to the concrete during mixing, after you have added the aggregates provided to the mixer. Adding the fibres before adding the aggregates may cause incorrect dispersal of fibres in the matrix. The dosage, depending on use, is normally between 0.6 and 1.2 kg per cubic metre of concrete. In the case of subbase screeds in sand/cement, the recommended dosage is about 750 g per cubic metre.
